flow_keys: Record IP layer protocol in skb_flow_dissect()
skb_flow_dissect() dissects only transport header type in ip_proto. It dose not give any information about IPv4 or IPv6. This patch adds new member, n_proto, to struct flow_keys. Which records the IP layer type. i.e IPv4 or IPv6. This can be used in netdev->ndo_rx_flow_steer driver function to dissect flow. Adding new member to flow_keys increases the struct size by around 4 bytes. This causes BUILD_BUG_ON(sizeof(qcb->data) < sz); to fail in qdisc_cb_private_validate() So increase data size by 4 Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S.
