OPNsense 21.1.2 likely to work with stock FreeBSD 12-STABLE kernel?

[crayon]

Hi,

I'm experiencing some network problems (see https://forum.opnsense.org/index.php?topic=21145.msg98865#msg98865) where my gut still tells me they may be related to the iflib'ified version of igb(4). I would like to check whether the problems also appear with a stock FreeBSD 12-STABLE kernel, since 12-STABLE contains a slew of fixes in that area that haven't been merged back to OPNsense yet.

Is a stock FreeBSD kernel likely to work with the OPNsense, or does the OPNsense depend on kernel extensions (e.g. tunables etc) not in FreeBSD?
