> Currently the driver does not recognize when there is an 802.1AD VLAN tag
> right after the dmac/smac (outermost VLAN tag). If any DCB map is applied
> and/or DCB is enabled this is causing the hardware to insert a VLAN 0 tag
> after the 802.1AD VLAN tag that is already in the packet.
> Fix this by preventing VLAN tag 0 from being added when any VLAN is
> already present after dmac/smac (software offloaded) or skb (hardware
> offloaded).
