The code in AF_PACKET should fix the skb before passing to user
space so that there is no difference between accel and non-accel
hardware.  Internal choices shouldn't leak to user space.  Ditto,
the receive checksum offload should be fixed up as well.

The hardware has stripped the VLAN header completely and has not
provided it to us at all.
Do the NICs not save the QoS bits in the VLAN header anywhere that we could
use to reconstitute the header?

Thanks,
Ben
