+ * The u-boot networking stack is a little weird. It seems like the
+ * networking core allocates receive buffers up front without any
+ * regard to the hardware that's supposed to actually receive those
+ * packets.
+ *
+ * The MACB receives packets into 128-byte receive buffers, so the
+ * buffers allocated by the core isn't very practical to use. We'll
+ * allocate our own, but we need one such buffer in case a packet
+ * wraps around the DMA ring so that we have to copy it.
+ *
+ * Therefore, define CFG_RX_ETH_BUFFER to 1 in the board-specific
+ * configuration header. This way, the core allocates one RX buffer
+ * and one TX buffer, each of which can hold a ethernet packet of
+ * maximum size.
+ *
+ * For some reason, the networking core unconditionally specifies a
+ * 32-byte packet "alignment" (which really should be called
+ * "padding"). MACB shouldn't need that, but we'll refrain from any
+ * core modifications here...

+ * NICE is designed to provide additional functionalities,

+ * the network device driver can be modified by adding an
+ * device ioctl handler and by indicating receiving packets
+ * to the NICE receive handler. Broadcom NICE will only be
+ * enabled by a NICE-aware intermediate driver, such as
+ * Broadcom Advanced Server Program Driver (BASP). When NICE
+ * is not enabled, the modified network device drivers
+ * functions exactly as other non-NICE aware drivers.

+/*
+ 28 Dec 2002 ken_yap@users.sourceforge.net (Ken Yap)
+ Put in virt_to_bus calls to allow Etherboot relocation.
+
+ 06 Apr 2001 ken_yap@users.sourceforge.net (Ken Yap)
+ Following email from Hyun-Joon Cha, added a disable routine, otherwise
+ NIC remains live and can crash the kernel later.
+
+ 4 Feb 2000 espenlaub@informatik.uni-ulm.de (Klaus Espenlaub)
+ Shuffled things around, removed the leftovers from the 8129 support
+ that was in the Linux driver and added a bit more 8139 definitions.
+ Moved the 8K receive buffer to a fixed, available address outside the
+ 0x98000-0x9ffff range. This is a bit of a hack, but currently the only
+ way to make room for the Etherboot features that need substantial amounts
+ of code like the ANSI console support. Currently the buffer is just below
+ 0x10000, so this even conforms to the tagged boot image specification,
+ which reserves the ranges 0x00000-0x10000 and 0x98000-0xA0000. My
+ interpretation of this "reserved" is that Etherboot may do whatever it
+ likes, as long as its environment is kept intact (like the BIOS
+ variables). Hopefully fixed rtl_poll() once and for all. The symptoms
+ were that if Etherboot was left at the boot menu for several minutes, the
+ first eth_poll failed. Seems like I am the only person who does this.
+ First of all I fixed the debugging code and then set out for a long bug
+ hunting session. It took me about a week full time work - poking around
+ various places in the driver, reading Don Becker's and Jeff Garzik's Linux
+ driver and even the FreeBSD driver (what a piece of crap!) - and
+ eventually spotted the nasty thing: the transmit routine was acknowledging
+ each and every interrupt pending, including the RxOverrun and RxFIFIOver
+ interrupts. This confused the RTL8139 thoroughly. It destroyed the
+ Rx ring contents by dumping the 2K FIFO contents right where we wanted to
+ get the next packet. Oh well, what fun.
+
+ 18 Jan 2000 mdc@thinguin.org (Marty Connor)
+ Drastically simplified error handling. Basically, if any error
+ in transmission or reception occurs, the card is reset.
+ Also, pointed all transmit descriptors to the same buffer to
+ save buffer space. This should decrease driver size and avoid
+ corruption because of exceeding 32K during runtime.
+
+ 28 Jul 1999 (Matthias Meixner - meixner@rbg.informatik.tu-darmstadt.de)
+ rtl_poll was quite broken: it used the RxOK interrupt flag instead
+ of the RxBufferEmpty flag which often resulted in very bad
+ transmission performace - below 1kBytes/s.

+ * grant unified interface. But PNMI macros will store the same
+ * value as RLMT macros.
+ *
+ * Revision 1.34 1999/04/13 15:03:49 mhaveman
+ * -Changed copyright
+ * -Removed SK_PNMI_RLMT_MODE_CHK_xxx macros. Those of RLMT should be
+ * used.
+ *
+ * Revision 1.33 1999/03/23 10:41:02 mhaveman
+ * Changed comments.
+ *
+ * Revision 1.32 1999/01/25 15:01:33 mhaveman
+ * Added support for multiple simultaniously active ports.
+ *
+ * Revision 1.31 1999/01/19 10:06:26 mhaveman
+ * Added new error log message.
+ *
+ * Revision 1.30 1999/01/05 10:34:49 mhaveman
+ * Fixed little error in RlmtChangeEstimate calculation.
+ *
+ * Revision 1.29 1999/01/05 09:59:41 mhaveman
+ * Redesigned port switch average calculation to avoid 64bit
+ * arithmetic.
+ *
+ * Revision 1.28 1998/12/08 10:05:48 mhaveman
+ * Defined macro SK_PNMI_MIN_STRUCT_SIZE.
+ *
+ * Revision 1.27 1998/12/03 14:39:35 mhaveman
+ * Fixed problem that LSTAT was enumerated wrong.
+ *
+ * Revision 1.26 1998/12/03 11:19:51 mhaveman
+ * Changed contents of errlog message SK_PNMI_ERR016MSG
+ *
+ * Revision 1.25 1998/12/01 10:40:04 mhaveman
+ * Changed size of SensorNumber, ChecksumNumber and RlmtPortNumber in
+ * SK_PNMI_STRUCT_DATA to be conform with OID definition.
+ *
+ * Revision 1.24 1998/11/20 08:09:27 mhaveman
+ * Added macros to convert between logical, physical port indexes and
+ * instances.
+ *
+ * Revision 1.23 1998/11/10 13:41:13 mhaveman
+ * Needed to change interface, because NT driver needs a return value
+ * of needed buffer space on TOO_SHORT errors. Therefore all
+ * SkPnmiGet/Preset/Set functions now have a pointer to the length
+ * parameter, where the needed space on error is returned.
+ *
+ * Revision 1.22 1998/11/03 12:05:51 mhaveman
+ * Added pAC parameter to counter macors.
+ *
+ * Revision 1.21 1998/11/02 10:47:36 mhaveman
+ * Added syslog messages for internal errors.
+ *
+ * Revision 1.20 1998/10/30 15:49:36 mhaveman
+ * -Removed unused SK_PNMI_UTILIZATION_BASE and EstOldCnt.
+ * -Redefined SK_PNMI_CHG_EST_BASE to hundreds of seconds.
+ *
+ * Revision 1.19 1998/10/29 15:38:44 mhaveman
+ * Changed string lengths of PNMI_STRUCT_DATA structure because
+ * string OIDs are now encoded with leading length ocetet.
+ *
+ * Revision 1.18 1998/10/29 08:52:27 mhaveman
+ * -Added byte to strings in PNMI_STRUCT_DATA structure.
+ * -Shortened SK_PNMI_RLMT structure to SK_MAX_MACS elements.
+ *
+ * Revision 1.17 1998/10/28 08:49:50 mhaveman
+ * -Changed type of Instance back to SK_U32 because of VPD
+ * -Changed type from SK_U8 to char of PciBusSpeed, PciBusWidth, PMD,
+ * and Connector.
+ *
+ * Revision 1.16 1998/10/22 10:42:31 mhaveman
+ * -Removed (SK_U32) casts for OIDs
+ * -excluded NDIS OIDs when they are already defined with ifndef _NDIS_
+ *
+ * Revision 1.15 1998/10/20 13:56:28 mhaveman
+ * Headerfile includes now directly other header files to comile correctly.
+ *
+ * Revision 1.14 1998/10/20 07:31:09 mhaveman
+ * Made type changes to unsigned int where possible.
+ *
+ * Revision 1.13 1998/10/19 10:53:13 mhaveman
+ * -Casted OID definitions to SK_U32
+ * -Renamed RlmtMAC... to RlmtPort...
+ * -Changed wrong type of VpdEntriesList from SK_U32 to char *
+ *
+ * Revision 1.12 1998/10/13 07:42:27 mhaveman
+ * -Added OIDs OID_SKGE_TRAP_NUMBER and OID_SKGE_ALL_DATA
+ * -Removed old cvs history entries
+ * -Renamed MacNumber to PortNumber
+ *
+ * Revision 1.11 1998/10/07 10:55:24 mhaveman
+ * -Added OID_MDB_VERSION. Therefore was a renumbering of the VPD OIDs
+ * necessary.
+ * -Added OID_GEN_ Ids to support the windows driver.
+ *
+ * Revision 1.10 1998/09/30 13:41:10 mhaveman
+ * Renamed some OIDs to reduce usage of 'MAC' which is replaced by 'PORT'.
+ *
+ * Revision 1.9 1998/09/04 17:06:17 mhaveman
+ * -Added SyncCounter as macro.
+ * -Renamed OID_SKGE_.._NO_DESCR_CTS to OID_SKGE_.._NO_BUF_CTS.
+ * -Added macros for driver description and version strings.
+ *
+ * Revision 1.8 1998/09/04 14:36:52 mhaveman

+ *
+ * SkCsGetSendInfo - get checksum information for a send packet
+ *
+ * Description:
+ * Get all checksum information necessary to send a TCP or UDP packet. The
+ * function checks the IP header passed to it. If the high-level protocol
+ * is either TCP or UDP the pseudo header checksum is calculated and
+ * returned.
+ *
+ * The function returns the total length of the IP header (including any
+ * IP option fields), which is the same as the start offset of the IP data
+ * which in turn is the start offset of the TCP or UDP header.
+ *
+ * The function also returns the TCP or UDP pseudo header checksum, which
+ * should be used as the start value for the hardware checksum calculation.
+ * (Note that any actual pseudo header checksum can never calculate to
+ * zero.)
+ *
+ * Note:
+ * There is a bug in the ASIC which may lead to wrong checksums.
+ *
+ * Arguments:
+ * pAc - A pointer to the adapter context struct.
+ *
+ * pIpHeader - Pointer to IP header. Must be at least the IP header *not*
+ * including any option fields, i.e. at least 20 bytes.
+ *
+ * Note: This pointer will be used to address 8-, 16-, and 32-bit
+ * variables with the respective alignment offsets relative to the pointer.
+ * Thus, the pointer should point to a 32-bit aligned address. If the
+ * target system cannot address 32-bit variables on non 32-bit aligned
+ * addresses, then the pointer *must* point to a 32-bit aligned address.
+ *
+ * pPacketInfo - A pointer to the packet information structure for this
+ * packet. Before calling this SkCsGetSendInfo(), the following field must
+ * be initialized:
+ *
+ * ProtocolFlags - Initialize with any combination of
+ * SKCS_PROTO_XXX bit flags. SkCsGetSendInfo() will only work on
+ * the protocols specified here. Any protocol(s) not specified
+ * here will be ignored.
+ *
+ * Note: Only one checksum can be calculated in hardware. Thus, if
+ * SKCS_PROTO_IP is specified in the 'ProtocolFlags',
+ * SkCsGetSendInfo() must calculate the IP header checksum in
+ * software. It might be a better idea to have the calling
+ * protocol stack calculate the IP header checksum.
+ *
+ * Returns: N/A
+ * On return, the following fields in 'pPacketInfo' may or may not have
+ * been filled with information, depending on the protocol(s) found in the
+ * packet:
+ *
+ * ProtocolFlags - Returns the SKCS_PROTO_XXX bit flags of the protocol(s)
+ * that were both requested by the caller and actually found in the packet.
+ * Protocol(s) not specified by the caller and/or not found in the packet
+ * will have their respective SKCS_PROTO_XXX bit flags reset.
+ *
+ * Note: For IP fragments, TCP and UDP packet information is ignored.
+ *
+ * IpHeaderLength - The total length in bytes of the complete IP header
+ * including any option fields is returned here. This is the start offset
+ * of the IP data, i.e. the TCP or UDP header if present.
+ *
+ * IpHeaderChecksum - If IP has been specified in the 'ProtocolFlags', the
+ * 16-bit Internet Checksum of the IP header is returned here. This value
+ * is to be stored into the packet's 'IP Header Checksum' field.
+ *
+ * PseudoHeaderChecksum - If this is a TCP or UDP packet and if TCP or UDP
+ * has been specified in the 'ProtocolFlags', the 16-bit Internet Checksum
+ * of the TCP or UDP pseudo header is returned here.

+ *
+ * Description:
+ * After calling this function the descriptor rings and Rx and Tx
+ * queues of this port may be reconfigured.
+ *
+ * It is possible to stop the receive and transmit path separate or
+ * both together.
+ *
+ * Dir = SK_STOP_TX Stops the transmit path only and resets the MAC.
+ * The receive queue is still active and
+ * the pending Rx frames may be still transferred
+ * into the RxD.
+ * SK_STOP_RX Stop the receive path. The tansmit path
+ * has to be stopped once before.
+ * SK_STOP_ALL SK_STOP_TX + SK_STOP_RX
+ *
+ * RstMode = SK_SOFT_RST Resets the MAC. The PHY is still alive.
+ * SK_HARD_RST Resets the MAC and the PHY.
+ *
+ * Example:
+ * 1) A Link Down event was signaled for a port. Therefore the activity
+ * of this port should be stopped and a hardware reset should be issued
+ * to enable the workaround of XMAC errata #2. But the received frames
+ * should not be discarded.
+ * ...
+ * SkGeStopPort(pAC, IoC, Port, SK_STOP_TX, SK_HARD_RST);
+ * (transfer all pending Rx frames)
+ * SkGeStopPort(pAC, IoC, Port, SK_STOP_RX, SK_HARD_RST);
+ * ...
+ *
+ * 2) An event was issued which request the driver to switch
+ * the 'virtual active' link to an other already active port
+ * as soon as possible. The frames in the receive queue of this
+ * port may be lost. But the PHY must not be reset during this
+ * event.
+ * ...
+ * SkGeStopPort(pAC, IoC, Port, SK_STOP_ALL, SK_SOFT_RST);
+ * ...
+ *
+ * Extended Description:
+ * If SK_STOP_TX is set,
+ * o disable the MAC's receive and transmitter to prevent
+ * from sending incomplete frames
+ * o stop the port's transmit queues before terminating the
+ * BMUs to prevent from performing incomplete PCI cycles
+ * on the PCI bus
+ * - The network Rx and Tx activity and PCI Tx transfer is
+ * disabled now.
+ * o reset the MAC depending on the RstMode
+ * o Stop Interval Timer and Limit Counter of Tx Arbiter,
+ * also disable Force Sync bit and Enable Alloc bit.
+ * o perform a local reset of the port's Tx path
+ * - reset the PCI FIFO of the async Tx queue
+ * - reset the PCI FIFO of the sync Tx queue
+ * - reset the RAM Buffer async Tx queue
+ * - reset the RAM Buffer sync Tx queue
+ * - reset the MAC Tx FIFO
+ * o switch Link and Tx LED off, stop the LED counters
+ *
+ * If SK_STOP_RX is set,
+ * o stop the port's receive queue
+ * - The path data transfer activity is fully stopped now.
+ * o perform a local reset of the port's Rx path
+ * - reset the PCI FIFO of the Rx queue
+ * - reset the RAM Buffer receive queue
+ * - reset the MAC Rx FIFO
+ * o switch Rx LED off, stop the LED counter
+ *
+ * If all ports are stopped,
+ * o reset the RAM Interface.
+ *
+ * Notes:
+ * o This function may be called during the driver states RESET_PORT and

+ * Revision 1.66 1999/08/26 13:47:56 rwahl
+ * Added SK_DRIVER_SENDEVENT when queueing RLMT_CHANGE_THRES trap.
+ *
+ * Revision 1.65 1999/07/26 07:49:35 cgoos
+ * Added two typecasts to avoid compiler warnings.
+ *
+ * Revision 1.64 1999/05/20 09:24:12 cgoos
+ * Changes for 1000Base-T (sensors, Master/Slave).
+ *
+ * Revision 1.63 1999/04/13 15:11:58 mhaveman
+ * Moved include of rlmt.h to header skgepnmi.h because some macros
+ * are needed there.
+ *
+ * Revision 1.62 1999/04/13 15:08:07 mhaveman
+ * Replaced again SK_RLMT_CHECK_LINK with SK_PNMI_RLMT_MODE_CHK_LINK
+ * to grant unified interface by only using the PNMI header file.
+ * SK_PNMI_RLMT_MODE_CHK_LINK is defined the same as SK_RLMT_CHECK_LINK.
+ *
+ * Revision 1.61 1999/04/13 15:02:48 mhaveman
+ * Changes caused by review:
+ * -Changed some comments
+ * -Removed redundant check for OID_SKGE_PHYS_FAC_ADDR
+ * -Optimized PRESET check.
+ * -Meaning of error SK_ADDR_DUPLICATE_ADDRESS changed. Set of same
+ * address will now not cause this error. Removed corresponding check.
+ *
+ * Revision 1.60 1999/03/23 10:41:23 mhaveman
+ * Added comments.
+ *
+ * Revision 1.59 1999/02/19 08:01:28 mhaveman
+ * Fixed bug 10372 that after counter reset all ports were displayed
+ * as inactive.
+ *
+ * Revision 1.58 1999/02/16 18:04:47 mhaveman
+ * Fixed problem of twisted OIDs SENSOR_WAR_TIME and SENSOR_ERR_TIME.
+ *
+ * Revision 1.56 1999/01/27 12:29:11 mhaveman
+ * SkTimerStart was called with time value in milli seconds but needs
+ * micro seconds.
+ *
+ * Revision 1.55 1999/01/25 15:00:38 mhaveman
+ * Added support to allow multiple ports to be active. If this feature in
+ * future will be used, the Management Data Base variables PORT_ACTIVE
+ * and PORT_PREFERED should be moved to the port specific part of RLMT.
+ * Currently they return the values of the first active physical port
+ * found. A set to the virtual port will actually change all active
+ * physical ports. A get returns the melted values of all active physical
+ * ports. If the port values differ a return value INDETERMINATED will
+ * be returned. This effects especially the CONF group.
+ *
+ * Revision 1.54 1999/01/19 10:10:22 mhaveman
+ * -Fixed bug 10354: Counter values of virtual port were wrong after port
+ * switches
+ * -Added check if a switch to the same port is notified.
+ *
+ * Revision 1.53 1999/01/07 09:25:21 mhaveman
+ * Forgot to initialize a variable.
+ *
+ * Revision 1.52 1999/01/05 10:34:33 mhaveman
+ * Fixed little error in RlmtChangeEstimate calculation.
+ *
+ * Revision 1.51 1999/01/05 09:59:07 mhaveman
+ * -Moved timer start to init level 2
+ * -Redesigned port switch average calculation to avoid 64bit
+ * arithmetic.
+ *
+ * Revision 1.50 1998/12/10 15:13:59 mhaveman
+ * -Fixed: PHYS_CUR_ADDR returned wrong addresses
+ * -Fixed: RLMT_PORT_PREFERED and RLMT_CHANGE_THRES preset returned
+ * always BAD_VALUE.
+ * -Fixed: TRAP buffer seemed to sometimes suddenly empty
+ *
+ * Revision 1.49 1998/12/09 16:17:07 mhaveman
+ * Fixed: Couldnot delete VPD keys on UNIX.
+ *
+ * Revision 1.48 1998/12/09 14:11:10 mhaveman
+ * -Add: Debugmessage for XMAC_RESET supressed to minimize output.
+ * -Fixed: RlmtChangeThreshold will now be initialized.
+ * -Fixed: VPD_ENTRIES_LIST extended value with unnecessary space char.
+ * -Fixed: On VPD key creation an invalid key name could be created
+ * (e.g. A5)
+ * -Some minor changes in comments and code.
+ *
+ * Revision 1.47 1998/12/08 16:00:31 mhaveman
+ * -Fixed: For RLMT_PORT_ACTIVE will now be returned a 0 if no port
+ * is active.
+ * -Fixed: For the RLMT statistics group only the last value was
+ * returned and the rest of the buffer was filled with 0xff
+ * -Fixed: Mysteriously the preset on RLMT_MODE still returned
+ * BAD_VALUE.
+ * Revision 1.46 1998/12/08 10:04:56 mhaveman
+ * -Fixed: Preset on RLMT_MODE returned always BAD_VALUE error.
+ * -Fixed: Alignment error in GetStruct
+ * -Fixed: If for Get/Preset/SetStruct the buffer size is equal or
+ * larger than SK_PNMI_MIN_STRUCT_SIZE the return value is stored
+ * to the buffer. In this case the caller should always return
+ * ok to its upper routines. Only if the buffer size is less
+ * than SK_PNMI_MIN_STRUCT_SIZE and the return value is unequal
+ * to 0, an error should be returned by the caller.
+ * -Fixed: Wrong number of instances with RLMT statistic.
+ * -Fixed: Return now SK_LMODE_STAT_UNKNOWN if the LinkModeStatus is 0.
+ *
+ * Revision 1.45 1998/12/03 17:17:24 mhaveman
+ * -Removed for VPD create action the buffer size limitation to 4 bytes.
+ * -Pass now physical/active physical port to ADDR for CUR_ADDR set
+ *
+ * Revision 1.44 1998/12/03 15:14:35 mhaveman
+ * Another change to Vpd instance evaluation.
+ *
+ * Revision 1.43 1998/12/03 14:18:10 mhaveman
+ * -Fixed problem in PnmiSetStruct. It was impossible to set any value.
+ * -Removed VPD key evaluation for VPD_FREE_BYTES and VPD_ACTION.
+ *
+ * Revision 1.42 1998/12/03 11:31:47 mhaveman
+ * Inserted cast to satisfy lint.
+ *
+ * Revision 1.41 1998/12/03 11:28:16 mhaveman
+ * Removed SK_PNMI_CHECKPTR
+ *
+ * Revision 1.40 1998/12/03 11:19:07 mhaveman
+ * Fixed problems
+ * -A set to virtual port will now be ignored. A set with broadcast
+ * address to any port will be ignored.
+ * -GetStruct function made VPD instance calculation wrong.
+ * -Prefered port returned -1 instead of 0.
+ *
+ * Revision 1.39 1998/11/26 15:30:29 mhaveman
+ * Added sense mode to link mode.
+ *
+ * Revision 1.38 1998/11/23 15:34:00 mhaveman
+ * -Fixed bug for RX counters. On an RX overflow interrupt the high
+ * words of all RX counters were incremented.
+ * -SET operations on FLOWCTRL_MODE and LINK_MODE accept now the
+ * value 0, which has no effect. It is usefull for multiple instance
+ * SETs.
+ *
+ * Revision 1.37 1998/11/20 08:02:04 mhaveman
+ * -Fixed: Ports were compared with MAX_SENSORS
+ * -Fixed: Crash in GetTrapEntry with MEMSET macro

+ * on Solaris.
+ *
+ * Revision 1.35 1998/11/16 07:45:34 mhaveman
+ * SkAddrOverride now returns value and will be checked.
+ *
+ * Revision 1.34 1998/11/10 13:40:37 mhaveman
+ * Needed to change interface, because NT driver needs a return value
+ * of needed buffer space on TOO_SHORT errors. Therefore all
+ * SkPnmiGet/Preset/Set functions now have a pointer to the length
+ * parameter, where the needed space on error is returned.
+ *
+ * Revision 1.33 1998/11/03 13:52:46 mhaveman
+ * Made file lint conform.
+ *
+ * Revision 1.32 1998/11/03 13:19:07 mhaveman
+ * The events SK_HWEV_SET_LMODE and SK_HWEV_SET_FLOWMODE pass now in
+ * Para32[0] the physical MAC index and in Para32[1] the new mode.
+ *
+ * Revision 1.31 1998/11/03 12:30:40 gklug
+ * fix: compiler warning memset
+ *
+ * Revision 1.30 1998/11/03 12:04:46 mhaveman
+ * Fixed problem in SENSOR_VALUE, which wrote beyond the buffer end
+ * Fixed alignment problem with CHIPSET.
+ *
+ * Revision 1.29 1998/11/02 11:23:54 mhaveman

+ * OID_SKGE_HW_VERSION, OID_SKGE_VPD_ENTRIES_LIST, OID_SKGE_VPD_KEY,
+ * OID_SKGE_VPD_VALUE, and OID_SKGE_SENSOR_DESCR return values with
+ * a leading octet before each string storing the string length.
+ * -Perform a RlmtUpdate during SK_PNMI_EVT_XMAC_RESET to minimize
+ * RlmtUpdate calls in GetStatVal.

+ * SK_PNMI_EVT_CHG_EST_TIMER The timer event was initiated by this

+ * SK_PNMI_EVT_CLEAR_COUNTER The event clears all counters and

+ * SK_PNMI_EVT_XMAC_RESET The event is generated by the driver
+ * before a hard reset of the XMAC is
+ * performed. All counters will be saved
+ * and added to the hardware counter
+ * values after reset to grant continuous
+ * counter values.
+ * SK_PNMI_EVT_RLMT_PORT_UP Generated by RLMT to notify that a port
+ * went logically up. A trap message will
+ * be stored to the trap buffer.
+ * SK_PNMI_EVT_RLMT_PORT_DOWN Generated by RLMT to notify that a port
+ * went logically down. A trap message will
+ * be stored to the trap buffer.
+ * SK_PNMI_EVT_RLMT_SEGMENTATION Generated by RLMT to notify that two
+ * spanning tree root bridges were
+ * detected. A trap message will be stored
+ * to the trap buffer.
+ * SK_PNMI_EVT_RLMT_ACTIVE_DOWN Notifies PNMI that an active port went
+ * down. PNMI will not further add the
+ * statistic values to the virtual port.
+ * SK_PNMI_EVT_RLMT_ACTIVE_UP Notifies PNMI that a port went up and
+ * is now an active port. PNMI will now
+ * add the statistic data of this port to
+ * the virtual port.
+ * SK_PNMI_EVT_RLMT_SET_NETS Notifies PNMI about the net mode. The first Parameter

+ *
+ * In the ISR of the driver the bits for frame transmission complete and
+ * for receive complete are checked and handled by the driver itself.
+ * The bits of the slow path mask are checked after that and then the
+ * entry into the so-called "slow path" is prepared. It is an implementors
+ * decision whether this is executed directly or just scheduled by
+ * disabling the mask. In the interrupt service routine some events may be
+ * generated, so it would be a good idea to call the EventDispatcher
+ * right after this ISR.
+ *
+ * The Interrupt source register of the adapter is NOT read by this module.
+ * SO if the drivers implementor needs a while loop around the
+ * slow data paths interrupt bits, he needs to call the SkGeSirqIsr() for
+ * each loop entered.
+ *
+ * However, the MAC Interrupt status registers are read in a while loop.

+ the serial EEPROM which hold the configuration.
+
+ This file covers functions that allow to read write and do
+ some bulk requests a specified I2C address.
+
+ The Genesis has 2 I2C buses. One for the EEPROM which holds
+ the VPD Data and one for temperature and voltage sensor.
+ The following picture shows the I2C buses, I2C devices and
+ their control registers.
+
+ Note: The VPD functions are in skvpd.c

+.
+ The I2C bus may be driven by the B2_I2C_SW or by the B2_I2C_CTRL
+ and B2_I2C_DATA registers.
+ For driver software it is recommended to use the I2C control and
+ data register, because I2C bus timing is done by the ASIC and
+ an interrupt may be received when the I2C request is completed.
+
+ Clock Rate Timing: MIN MAX generated by
+ VPD EEPROM: 50 kHz 100 kHz HW
+ LM80 over I2C Ctrl/Data reg. 50 kHz 100 kHz HW
+ LM80 over B2_I2C_SW register 0 400 kHz SW
+
+ Note: The clock generated by the hardware is dependend on the
+ PCI clock. If the PCI bus clock is 33 MHz, the I2C/VPD
+ clock is 50 kHz.
