Zhengchao Shao ec274d8f1e net/af_packet: check len when min_header_len equals to 0 
commit dc633700f00f726e027846a318c5ffeb8deaaeda upstream.

User can use AF_PACKET socket to send packets with the length of 0.
When min_header_len equals to 0, packet_snd will call __dev_queue_xmit
to send packets, and sock->type can be any type.

Fixes: fd1894224407 ("bpf: Don't redirect packets with invalid pkt_len")
