We liked the fact that the Chelsio cards were single-port and cheaper. I
don't really understand why nearly all 10GBE cards are dual-port. Surely
there is a market for NICs between 1 gigabit and 20 gigabit.
The NIC heatsinks are too hot to touch during use unless specially c

Existing prior connections will continue to to through the first

Where client src connects to server dst, and you create the state entry
when the initial TCP SYN goes out $ext_if on the firewall?
The ICMPv6 is coming in on $ext_if, in the reverse direction, relative

There could be random garbage there, and the bit corresponding to
TH_SYN might be set, so the window scale factor is not applied. Not sure
if that would be reproducable so reliably, but it sure is a bug ;)

knows, that byte might contain a MAC address, and you happen to have a
NIC with a specific MAC address byte ;)
There's nothing wrong with the router, the bug is in pf. Let me know if
anything changes, or when you're sure that the problem is resolved.
Thanks for your help!

The problem is the lack of IP reassembly in this configuration.
In pf_test_fragment(), a rule with r->flagset ("flags S/SA") is skipped.
