 *	                              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.

 *	                              timestamps.
 *	SK_PNMI_EVT_XMAC_RESET        The event is generated by the driver
 *	                              before a hard reset of the XMAC is

 *	                              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

 *      SkPnmiGenIoctl - Handles new generic PNMI IOCTL, calls the needed
 *                       PNMI function depending on the subcommand and
 *                       returns all data belonging to the complete database
 *                       or OID request.
 *
 * Description:
 *	Looks up the requested subcommand, calls the corresponding handler
 *	function and passes all required parameters to it.
 *	The function is called by the driver. It is needed to handle the new
 *  generic PNMI IOCTL. This IOCTL is given to the driver and contains both
 *  the OID and a subcommand to decide what kind of request has to be done.
 *
 * Returns:
 *	SK_PNMI_ERR_OK           The request was successfully performed
 *	SK_PNMI_ERR_GENERAL      A general severe internal error occured
 *	SK_PNMI_ERR_TOO_SHORT    The passed buffer is too short to take
 *	                         the data.
 *	SK_PNMI_ERR_UNKNOWN_OID  The requested OID is unknown
 *	SK_PNMI_ERR_UNKNOWN_INST The requested instance of the OID doesn't
 *                           exist (e.g. port instance 3 on a two port
