ipv6: add priority parameter to ip6_xmit()
Currently, ip6_xmit() sets skb->priority based on sk->sk_priority This is not desirable for TCP since TCP shares the same ctl socket for a given netns. We want to be able to send RST or ACK packets with a non zero skb->priority. This patch has no functional change. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
