Subject: tg3: Allow for recieve of full-size 8021AD frames
From: Vlad Yasevich <vyasevich@xxxxxxxxx>
[ Upstream commit 7d3083ee36b51e425b6abd76778a2046906b0fd3 ]
When receiving a vlan-tagged frame that still contains
a vlan header, the length of the packet will be greater
then MTU+ETH_HLEN since it will account of the extra
vlan header. TG3 checks this for the case for 802.1Q,
but not for 802.1ad. As a result, full sized 802.1ad
frames get dropped by the card.
Add a check for 802.1ad protocol when receving full
sized frames.
