I'm not aware of any AX.25 protocol support that ships as part of
standard BSD network stack (but I could be surprised). You could
write your own protocol handler based on whatever open source is
available, but that's a lot of work. It's probably easier to use a
PF_NDRV socket (raw driver access) to extract the frames right to
your user process and decode them from there.

Actually, I wouldn't be getting the byte stream from the network. I'd
have to get it from a serial port or USB device. I wanted to then feed
that into the network protocol stack (assuming it had AX.25 support),
but I really have no idea how I'd do that.
(This approach was suggested to me by someone who wrote an audio
decoder for various digital radio transmission modes.)
I think Linux has AX.25 in it's network stack; I had hoped that would
mean it was already in Darwin, or possibly easy to add.
Thanks, anyway.
