Is there a reason why skb->len for skb->pkt_type=PACKET_OUTGOING is 14 bytes 
larger than for skb->pkt_type=PACKET_HOST?  I doubt its a coincidence that the 
size of the ethernet header is 14 bytes.  Also, I notice that skb->data starts 
at a different location (relative to the ethernet header) if its outgoing 
compared to incoming traffic.  Can anyone tell me why?

Regards,
Mazhar
