Willem de Bruijn 24ee394a82 packet: only test po->has_vnet_hdr once in packet_snd ... [ Upstream commit da7c956101 ] Packet socket option po->has_vnet_hdr can be updated concurrently with other operations if no ring is attached. Do not test the option twice in packet_snd, as the value may change in between calls. A race on setsockopt disable may cause a packet > mtu to be sent without having GSO options set.
