I did notice that, but I left it in place because (a) it comes down the stack with the NET_IP_ALIGNment and (b) ARP is only sent over Ethernet II (there is no LLC SAP for ARP, which is a big reason why ipv4 is not sent over llc, despite rfc 1042). I figured it would not hurt to pass it down, in case we decide to do something clever with it in the future. --Sowmini
