Willem de Bruijn a200e439c0 net/packet: tpacket_rcv: do not increment ring index on drop ... [ Upstream commit 46e4c421a0 ] In one error case, tpacket_rcv drops packets after incrementing the ring producer index. If this happens, it does not update tp_status to TP_STATUS_USER and thus the reader is stalled for an iteration of the ring, causing out of order arrival. The only such error path is when virtio_net_hdr_from_skb fails due to encountering an unknown GSO type. Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.
