+ * @brief   Header file for the IXP400 ATM Traffic Shaper
+ *
+ * This component demonstrates an ATM Traffic Shaper implementation. It
+ * will perform shaping on upto 12 ports and total of 44 VCs accross all ports,
+ * 32 are intended for AAL0/5 and 12 for OAM (1 per port).
+ * The supported traffic types are;1 rt-VBR VC where PCR = SCR.
+ * (Effectively CBR) and Up-to 44 VBR VCs.
+ *
+ * This component models the ATM ports and VCs and is capable of producing
+ * a schedule of ATM cells per port which can be supplied to IxAtmdAcc
+ * for execution on the data path.

+ *
+ * @defgroup IxAtmdAccAPI IXP400 ATM Driver Access (IxAtmdAcc) API
+ *
+ * @brief The public API for the IXP400 Atm Driver Data component
+ *
+ * IxAtmdAcc is the low level interface by which AAL0/AAL5 and
+ * OAM data gets transmitted to,and received from the Utopia bus.
+ *
+ * For AAL0/AAL5 services transmit and receive connections may
+ * be established independantly for unique combinations of
+ * port,VPI,and VCI.
+ *
+ * Two AAL0 services supporting 48 or 52 byte cell data are provided.
+ * Submitted AAL0 PDUs must be a multiple of the cell data size (48/52).
+ * AAL0_52 is a raw cell service the client must format
+ * the PDU with an ATM cell header (excluding HEC) at the start of
+ * each cell, note that AtmdAcc does not validate the cell headers in
+ * a submitted PDU.
+ *
+ * OAM cells cannot be received over the AAL0 service but instead
+ * are received over a dedicated OAM service.
+ *
+ * For the OAM service an "OAM Tx channel" may be enabled for a port
+ * by establishing a single dedicated OAM Tx connection on that port.
+ * A single "OAM Rx channel" for all ports may be  enabled by
+ * establishing a dedicated OAM Rx connection.
+ *
+ * The OAM service allows buffers containing 52 byte OAM F4/F5 cells
+ * to be transmitted and received over the dedicated OAM channels.
+ * HEC is appended/removed, and CRC-10 performed by the NPE. The OAM
+ * service offered by AtmdAcc is a raw cell transport service.
+ * It is assumed that ITU I.610 procedures that make use of this
+ * service are implemented above AtmdAcc.
+ *
+ * Note that the dedicated OAM connections are established on
+ * reserved VPI,VCI, and (in the case of Rx) port values defined below.
+ * These values are used purely to descriminate the dedicated OAM channels
+ * and do not identify a particular OAM F4/F5 flow. F4/F5 flows may be
+ * realised for particluar VPI/VCIs by manipulating the VPI,VCI
+ * fields of the ATM cell headers of cells in the buffers passed
+ * to AtmdAcc. Note that AtmdAcc does not validate the cell headers
+ * in a submitted OAM PDU.

+ * The database record is identified using a combination of the given parameters, depending on the record type.
+ * All the record types require the record MAC address.
+ *
+ * - IX_ETH_DB_FILTERING_RECORD requires only the MAC address
+ * - IX_ETH_DB_VLAN_FILTERING_RECORD requires the MAC address and the VLAN ID
+ * - IX_ETH_DB_WIFI_RECORD requires the MAC address and the portID
+ * - IX_ETH_DB_FIREWALL_RECORD requires the MAC address and the portID
+ *
+ * Please note that if a parameter is not required it is completely ignored (it does not undergo parameter checking).
+ *
+ * If no user-defined field was registered with the specified record then <b>NULL</b> will be written
+ * at the location specified by <i>field</i>.
+ *
+ * @param recordType type of record (can be IX_ETH_DB_FILTERING_RECORD, IX_ETH_DB_FILTERING_VLAN_RECORD, IX_ETH_DB_WIFI_RECORD 
+ * or IX_ETH_DB_FIREWALL_RECORD)
+ * @param portID ID of the port (required only for WIFI and FIREWALL records) 
+ * @param macAddr MAC address of the record
+ * @param vlanID VLAN ID of the record (required only for FILTERING_VLAN records)
+ * @param field location to write the user defined field into
+ * 
+ * @retval IX_ETH_DB_SUCCESS operation completed successfully

+ * The main intent of this API is to inplement MII high level fonctionalitoes
+ * to support the codelets provided with the IXP400 software releases. It 
+ * superceedes previous interfaces provided with @ref IxEThAcc component.
+ * 
+ * This API has been tested with the PHYs provided with the
+ * IXP400 development platforms. It may not work for specific Ethernet PHYs
+ * used on specific boards.
+ *
+ * This source code detects and interface the LXT972, LXT973 and KS6995
+ * Ethernet PHYs.
+ *
+ * This source code should be considered as an example which may need
+ * to be adapted for different hardware implementations.
+ *
+ * It is strongly recommended to use public domain and GPL utilities
+ * like libmii, mii-diag for MII interface support.

+ *
+ * IxHssAcc is the access layer to the HSS packetised and channelised
+ * services
+ * 
+ * <b> Design Notes </b><br>
+ * <UL>
+ * <LI>When a packet-pipe is configured for 56Kbps RAW mode, byte alignment of 
+ *     the transmitted data is not preserved. All raw data that is transmitted 
+ *     will be received in proper order by the receiver, but the first bit of 
+ *     the packet may be seen at any offset within a byte; all subsequent bytes 
+ *     will have the same offset for the duration of the packet. The same offset 
+ *     also applies to all subsequent packets received on the packet-pipe too. 
+ *     (Similar results will occur for data received from remote end.) While 
+ *     this behavior will also occur for 56Kbps HDLC mode, the HDLC 
+ *     encoding/decoding will preserve the original byte alignment at the 
+ *     receiver end.
+ * </UL>
+ *
+ * <b> 56Kbps Packetised Service Bandwidth Limitation </b><br>
+ * <UL>
+ * <LI>IxHssAcc supports 56Kbps packetised service at a maximum aggregate rate
+ *     for all HSS ports/HDLC channels of 12.288Mbps[1] in each direction, i.e.
+ *     it supports 56Kbps packetised service on up to 8 T1 trunks. It does
+ *     not support 56Kbps packetised service on 8 E1 trunks (i.e. 4 trunks per 
+ *     HSS port) unless those trunks are running 'fractional E1' with maximum 
+ *     aggregate rate of 12.288 Mbps in each direction.<br>
+ *     [1] 12.288Mbps = 1.536Mbp * 8 T1

+ * This module contains the implementation of the OS Services buffer pool
+ * management service.  This module provides routines for creating pools
+ * of buffers for exchange of network data, getting and returning buffers
+ * from and to the pool, and some other utility functions. 
+ * <P>
+ * Currently, the pool has 2 underlying implementations - one for the vxWorks
+ * OS, and another which attempts to be OS-agnostic so that it can be used on
+ * other OS's such as Linux.  The API is largely the same for all OS's,
+ * but there are some differences to be aware of.  These are documented
+ * in the API descriptions below.
+ * <P>
+ * The most significant difference is this: when this module is used with
+ * the WindRiver VxWorks OS, it will create a pool of vxWorks "MBufs".
+ * These can be used directly with the vxWorks "netBufLib" OS Library.
+ * For other OS's, it will create a pool of generic buffers.  These may need
+ * to be converted into other buffer types (sk_buff's in Linux, for example)
+ * before being used with any built-in OS routines available for
+ * manipulating network data buffers.

+ *
+ * @date    30-Oct-2001
+ *
+ * @brief This file contains the public API of IxQMgr component.
+ *
+ * Some functions contained in this module are inline to achieve better
+ * data-path performance. For this to work, the function definitions are
+ * contained in this header file. The "normal" use of inline functions
+ * is to use the inline functions in the module in which they are
+ * defined. In this case these inline functions are used in external
+ * modules and therefore the use of "inline extern". What this means
+ * is as follows: if a function foo is declared as "inline extern" this
+ * definition is only used for inlining, in no case is the function
+ * compiled on its own. If the compiler cannot inline the function it
+ * becomes an external reference. Therefore in IxQMgrQAccess.c all
+ * inline functions are defined without the "inline extern" specifier
+ * and so define the external references. In all other source files
+ * including this header file, these funtions are defined as "inline
+ * extern".

+ *
+ * @author Intel Corporation
+ * @date    30-Oct-2001
+ *
+ * @brief   The IxQMgrAqmIf sub-component provides a number of inline
+ * functions for performing I/O on the AQM. 
+ *
+ * Because  some functions contained in this module are inline and are
+ * used in other modules (within the QMgr component) the definitions are
+ * contained in this header file. The "normal" use of inline functions
+ * is to use the inline functions in the module in which they are
+ * defined. In this case these inline functions are used in external
+ * modules and therefore the use of "inline extern". What this means
+ * is as follows: if a function foo is declared as "inline extern"this
+ * definition is only used for inlining, in no case is the function
+ * compiled on its own. If the compiler cannot inline the function it
+ * becomes an external reference. Therefore in IxQMgrAqmIf.c all
+ * inline functions are defined without the "inline extern" specifier
+ * and so define the external references. In all other modules these
+ * funtions are defined as "inline extern".

+ *
+ *    The timer callback control component provides a mechanism by which different 
+ *    client components can start a timer and have a supplied callback function
+ *    invoked when the timer expires.
+ *    The callbacks are all dispatched from one thread inside this component. 
+ *    Any component that needs to be called periodically should use this facility 
+ *    rather than create its own task with a sleep loop.

+ *
+ * = MODULE
+ *      OSSL  Abstraction layer header file
+ *
+ * = FILENAME
+ *       ix_ossl.h (Replaced by OSAL)
+ *
+ * = DESCRIPTION
+ *   This file contains the prototypes of OS-independent wrapper
+ *   functions which allow the programmer not to be tied to a specific
+ *   operating system. The OSSL functions can be divided into three classes:
+ *
+ *   1) synchronization-related wrapper functions around thread system calls
+ *   2) thread-related wrapper functions around thread calls
+ *   3) transactor/workbench osapi calls -- defined in osApi.h
+ *
+ *   Both 1 and 2 classes of functions provide Thread Management, Thread 
+ *   Synchronization, Mutual Exclusion and  Timer primitives. Namely, 
+ *   creation and deletion functions as well as the standard "wait" and
+ *   "exit". Additionally, a couple of utility functions which enable to 
+ *   pause the execution of a thread are also provided.
+ *
+ *   The 3rd class provides a  slew of other OSAPI functions to handle
+ *   Transactor/WorkBench OS calls.
+ *
+ *
+ *   OSSL Thread APIs:
+ *             The OSSL thread functions that allow for thread creation,
+ *             get thread id, thread deletion and set thread priroity.
+ *
+ *             ix_ossl_thread_create
+ *             ix_ossl_thread_get_id
+ *             ix_ossl_thread_exit
+ *             ix_ossl_thread_kill
+ *             ix_ossl_thread_set_priority
+ *             ix_ossl_thread__delay
+ * 
+ *   OSSL Semaphore APIs:
+ *             The OSSL semaphore functions that allow for initialization,
+ *             posting, waiting and deletion of semaphores.
+ *
+ *             ix_ossl_sem_init
+ *             ix_ossl_sem_fini
+ *             ix_ossl_sem_take
+ *             ix_ossl_sem_give
+ *             ix_ossl_sem_flush
+ *
+ *   OSSL Mutex APIs:
+ *             The OSSL wrapper functions that allow for initialization,
+ *             posting, waiting and deletion of mutexes.
+ *
+ *             ix_ossl_mutex_init
+ *             ix_ossl_mutex_fini
+ *             ix_ossl_mutex_lock
+ *             ix_ossl_mutex_unlock
+ *
+ *   OSSL Timer APIs:
+ *     	       The timer APIs provide sleep and get time functions.
+ *
+ *             ix_ossl_sleep
+ *             ix_ossl_sleep_tick
+ *             ix_ossl_time_get
+ * 
+ *   OSAPIs for Transactor/WorkBench:
+ *             These OSAPI functions are used for transator OS calls. 
+ *             They are defined in osApi.h. 
+ *
+ *             Sem_Init 			
+ *             Sem_Destroy 		
+ *             Sem_Wait
