A network interface.

Isn't going to happen.  We don't have any code to gate between
network feeds.

Yep.  That's a great clue that it's the wrong type of interface for
what you're wanting to do.

But could be the direct feed from LOTS of TNC's...  With the current
AGWPE code, if you had more than one TNC under AGWPE's control, ALL
of the packets from all AGWPE-connected TNC's would get received by
Xastir on that one interface.  If you had multiple connections to
AGWPE you'd be getting duplicate packets from each interface.
There's no way to separate them out to individual TNC streams.  We
could redo the code to fix this of course, either by throwing away
packets that didn't come in on that interface, or perhaps by coding
to a different AGPWE API, but we haven't done so.  We don't have a
high percentage of people using this interface.

Yes.

Patches to the code.  Perhaps several.
