// Interface to allow G8BPQ switch to use ARDOP Virtual TNC in a form
// of ax.25
// Uses a lot of routines in ARDOP.c
// Includes its own ax.25 L2 stack, as I want to do dynamic packet size and
// maxframe
// Actually may be better to use existing L2, but modify for dynamic paclen, but we
// need tighter coupling than the KISS driver provides. So this may become a "SuperKISS" TNC
// as a minimum I think this needs channel busy info connected to L2. Not sure yet!!
