    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 <>

    [ 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
