Some porters don't mind support (e.g. https://gitlab.fechner.net/mfechner/Gitlab-docu/blob/master/install/16.10-freebsd.md#support-me ). However, we won't know how good these changes are without hands-on experimentation.

The patch works like a charm! This fixes the case I described here (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235556#c2), the stats are now correct: https://www.bsdstore.ru/trash/racct.png

Hi, Checked the vether module for a month under high load ( 13-CURRENT ). I can say that at present this is the only stable way to interact with traffic inside the VALE switch from the host system. if_epair is extremely unstable. It would be very helpful to see the movement of this work.

@novel I checked this patch on my system and it looks good for me.

Probably a good idea to make it tunable and also, it would be nice if the system checks the amount of firmware and noticed message about limit exceed, instead of 'Invalid argument'
