 *	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.
 *

 *	Replaced again SK_RLMT_CHECK_LINK with SK_PNMI_RLMT_MODE_CHK_LINK

 *	
 *	Revision 1.60  1999/03/23 10:41:23  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

 *
 *	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

 *	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.
 *

 *	 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.
