From 97a7a37a7b7bf3dd16f6fa13cfd7ffacd01a352f Mon Sep 17 00:00:00 2001 From: Chenbo Feng Date: Fri, 9 Jun 2017 12:06:07 -0700 Subject: ipv6: Initial skb->dev and skb->protocol in ip6_output Move the initialization of skb->dev and skb->protocol from ip6_finish_output2 to ip6_output. This can make the skb->dev and skb->protocol information avalaible to the CGROUP eBPF filter. Signed-off-by: Chenbo Feng Acked-by: Eric Dumazet Signed-off-by: David S.
