 *	                              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

 *	                              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

 *	                              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
