dev: add per net_device packet type chains
When many pf_packet listeners are created on a lot of interfaces the current implementation using global packet type lists scales poorly. This patch adds per net_device packet type lists to fix this problem. The patch was originally written by Eric Biederman for linux-2.6.29. Tested on linux-3.16. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: Salam Noureddine <noureddine@arista.com> Signed-off-by: David S. Miller <davem@davemloft.net>
