288 * are part of SysKonnect's COMMON MODULES for the SK-98xx adapters.
289 * Those are used for drivers on multiple OS', so some thing may seem
290 * unnecessary complicated on Linux. Please do not try to 'clean up'
291 * them without VERY good reasons, because this will make it more
292 * difficult to keep the Linux driver in synchronisation with the
293 * other versions.

2088 * The second part is linking the buffer to the descriptor.
2089 * At the very last, the Control field of the descriptor
2090 * is made valid for the BMU and a start TX command is given
2091 * if necessary.
2092 *
2093 * Returns:
