The router in question runs netbsd-3 now (the PR is against ipfilter
1.3.29 as found in netbsd-1-6). The RedHat machines that triggered the
bug are gone from our network, so I have no means any more of
testing/reproducing the problem.
Since Darren seems too busy to pick up the tcpdump tarball, or even
update the status of the pr, I ask for this PR to be closed.
