In addition to the current multicast route actions, which include trap route action and a forward route action, add the trap-and-forward multicast route action, and implement it in the multicast routing hardware logic. To implement that, add a trap-and-forward ACL action as the last action in the route flexible action set. The used trap is the ACL2 trap, which marks the packets with offload_mr_forward_mark, to prevent the packet from being forwarded again by the kernel. Note: At that stage the offloading logic does not support trap-and-forward multicast routes. This patch adds the support only in the hardware logic.
