Log Message:
Pull up revision 1.7 (requested by jonathan in ticket #283):
Commit an old diff for AH which has been in my personal tree since
August 2003:
On NetBSD, when we get to ah_massage_headers(), ip->ip_len is in
network byte order and includes all bytes in the input packet.
Therefore we don't need to byte-swap it or to add `skip' back in,
before verifying the receive-side hash.
With this change, AH transport mode works against FreeBSD 4.9 fast-ipsec
(which also works against Win2k, &c., &c.).
