After converting both sides to using syncpeer, I now got this in my
dmesg after reboot:
<snip most of dmesg you've already seen>

The other pfsyncstats.pfsyncs_oerrors++ is after a IF_HANDOFF macro, I
traced it back to if_handoff() in if.c, but I'm not sure how to track
it down any further as it look like it's _IF_QFULL(ifq) that's
triggering the return 0.
I'm going to toy with some settings for the em(4) driver in
loader.conf and see if I can raise the txd and rxd descriptors since
we're not running on 82542 or 82543 chipped hardware we can go above
256 descriptors.
