 *	mechanism you get the best results when software corrections for
 *	counters are needed. Example: RX_LONGFRAMES.

 *
 *	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

 *	        always BAD_VALUE.

 *
 *	Revision 1.49  1998/12/09 16:17:07  mhaveman

 *		BAD_VALUE.

 *	-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

 *
 *	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.

 *	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

 *	 OID_SKGE_VPD_VALUE, and OID_SKGE_SENSOR_DESCR return values with
 *	 a leading octet before each string storing the string length.
