Log:
MFC r226105:
Add back the IP header length to the total packet length field on
raw IP sockets. It was deducted in ip_input() in preparation for
protocols interested only in the payload.
On raw sockets the IP header should be delivered as it at came in
from the network except for the byte order swaps in some fields.
