Subject: [187/244] vlan: reset headers on accel emulation path
3.0-stable review patch. If anyone has any objections, please let us know.
------------------
From: Jiri Pirko <jpirko@...hat.com>
[ 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
