I have been using mesa Ethernet cards from their inception.   I think I can
count on one hand the number of times linuxcnc couldn't find the card.  (
and they were probably my fault). Except for the really early days when you
had to build rt_preemp - I mostly use the linuxcnc stretch livecd for my
installs.  I am also using the 7i92 on the pi4 and don't remember it not
being found.
