Any of you who are expereincing problems with packets dropped due to
invalid checksums with IPv6 and pf after the recent merges, can you
report back if you also see this without "modulate state" in your
pf.conf (if you have 'modulate' in there, can you try changing it to
'keep' and see if that fixes the problem)?
