I've got a machine that's collecting logs via syslog-ng and it's crashing about once a day in
in_cksum().  I don't have a traceback for it yet.  I'll get that when it crashes again and I'll
file a PR.

Also, in a attempt to work around these crashes, I've turned off UDP checksums this morning:

  sysctl -w net.inet.udp.checksum=0


The machine in question is an X86 running NetBSD 2.99.11 as of Dec 20 (both kernel and userland)
