Starting with 10.0, our stack doesn't change byte order of IP packets, so if my guessing is right, the bug should vanish. We do not plan any more releases from stable/8 branch. Thus, I'd like to close the PR if you don't mind. -- Totus tuus, Glebius. _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
