From b082a5631a746b494553f7c72b387cb625a1674a Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Thu, 18 Aug 2011 21:29:27 -0700 Subject: vlan: reset headers on accel emulation path [ Upstream commit c5114cd59d2664f258b0d021d79b1532d94bdc2b ] It's after all necessary to do reset headers here. The reason is we cannot depend that it gets reseted in __netif_receive_skb once skb is reinjected. For incoming vlanids without vlan_dev, vlan_do_receive() returns false with skb != NULL and __netif_reveive_skb continues, skb is not reinjected. This might be good material for 3.0-stable as well Reported-by: Mike Auty Signed-off-by: Jiri Pirko Signed-off-by: David S.
