* And L2 should not pull off L2 header when combination of socket
* like this AF_PACKET, SOCK_RAW and ETH_P_ALL proto.
* 2) Socket combination of AF_INET, SOCK_RAW, IPPROTO_RAW
* packet has to go through L2 and L2 verfies it's header and removes
* header. Only packet with L3 header will be given to socket.
* 3) If user opens raw and non raw socket together, based on raw
* socket combination packet has to be feed to raw socket and only
* data part to be feed to non raw socket.
