CVS commit: src/sys/netipsec

Module Name:    src
Committed By:   drochner
Date:           Thu Feb 10 20:42:30 UTC 2011

Modified Files:
        src/sys/netipsec: ipsec_output.c

Log Message:
in rev.1.192 of ip_output.c the semantics of ip_output() was changed:
Before, setting the IP_RAWOUTPUT flag did imply that the ip_id
(the fragmentation thing) was used as-is.
Now, a new ID is diced unless the new IP_NOIPNEWID flag is set.
The ip_id is part of the data which are used to calculate the hash
for AH, so set the IP_NOIPNEWID flag to make sure the IP header
is not modified behind AH's back. Otherwise, the recipient will detect
a checksum mismatch and discard the packet.
