When ip_frag_queue() computes positions, it assumes that the passed
sk_buff does not contain L2 headers. However, when
PACKET_FANOUT_FLAG_DEFRAG is used, IP defragmentation functions can be
called on outgoing packets that contain L2 headers. Also, IPv4
checksum is not corrected after defragmentatio

This was meant to be
ip_send_check(iph);
Sorry, will send a v2
