Currently, hardware VLAN stripping is broken for 802.1ad tags. vlan_rx_hw() hardcodes ETH_P_8021Q when putting the hardware tag into the skb, rather than using the actual protocol from the packet. Because of this, packets that contain an 802.1ad outer tag are incorrectly passed up the stack as having an 802.1Q tag.
Test LGTM, let me apply just the test since it looks like the driver part will need a respin.
