Perhaps it should be changed. e100 calculates the entire
frame as far as I can tell, and e1000 and tg3 do it in hardware
(not sure what all they are counting, but I *think* it includes
the header...)
VLANs calculate before pulling it's header, though the ethernet
header has already been pulled by the time VLAN sees the skb.
Thanks,
Ben
