oops I was half asleep

Driver sets

skb->mac.raw
skb->pkt_type
skb->protocol
(see net/ethernet/eth.c)

skb->h.raw and skb->nh.raw are set by the receive action code

On transmit

nh.raw is set by the protocol

Note that non -ac kernels have a bug where a packet consisting of pure mac
header causes bogus warnings
