wireguard-freebsd handshaking issue upon underlying WAN

[Jason A. Donenfeld]

Hi Ryan,

Thanks for the report. Kyle saw your reddit post earlier and tracked
this down, I think/hope, to a bug in the state machine cranking. I
committed the fix here -- https://w-g.pw/l/yQTw -- which will be part
of the next snapshot. Hopefully that will fix the issue, but if it
doesn't, please do update this thread so we can keep searching.

Regards,
Jason
