 *	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

 *	 arithmetic.
 *
 *	Revision 1.50  1998/12/10 15:13:59  mhaveman
 *	-Fixed: PHYS_CUR_ADDR returned wrong addresses

 *	        always BAD_VALUE.
 *	-Fixed: TRAP buffer seemed to sometimes suddenly empty
 *
 *	Revision 1.49  1998/12/09 16:17:07  mhaveman

 *		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 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.

 *	on Solaris.
 *

 *	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.

 *	 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.

 *	                              upper 32 bit of the 64 bit counter.
 *	SK_PNMI_EVT_SEN_XXX           The event is generated by the I2C module
 *	                              when a sensor reports a warning or
 *	                              error. The event will store a trap

 *	SK_PNMI_EVT_CHG_EST_TIMER     The timer event was initiated by this

 *	                              port switches per hour.
 *	SK_PNMI_EVT_CLEAR_COUNTER     The event clears all counters and
 *	                              timestamps.
 *	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

 *	                              went logically down. A trap message will
 *	                              be stored to the trap buffer.

 *	                              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
