		/* Trap Action
		* -----------
		/* Trap Action / Trap With Userdef Action
		* --------------------------------------
		* The Trap action enables trapping / mirroring packets to the CPU
		* as well as discarding packets.
		* The ACL Trap / Discard separates the forward/discard control from CPU
		* trap control. In addition, the Trap / Discard action enables activating
		* SPAN (port mirroring).
		*
		* The Trap with userdef action action has the same functionality as
		* the Trap action with addition of user defined value that can be set
		* and used by higher layer applications.
