+Using code from 6pack Linux Kernel driver with the following licence and credits

+ *
+ * 		This module implements the AX.25 protocol for kernel-based
+ *		devices like TTYs. It interfaces between a raw TTY, and the
+ *		kernel's AX.25 protocol layers, just like slip.c.
+ *		AX.25 needs to be separated from slip.c while slip.c is no
+ *		longer a static kernel device since it is a module.
+ *
+ *	Author: Andreas Könsgen <ajk@ccac.rwth-aachen.de>
+ *
+ *	Lots of stuff has been taken from mkiss.c, written by
+ *	Hans Alblas <hans@esrac.ele.tue.nl>
+ *
+ *	with the fixes from
+ *
+ *	Jonathan (G4KLX)	Fixed to match Linux networking changes - 2.1.15.
+ *	Matthias (DG2FEF)       Fixed bug in ax25_close(): dev_lock_wait() was
+ *                              called twice, causing a deadlock.

+ //	6pack needs fast response to received characters, and I want to be able to operate over TCP links as well as serial.
+ //	So I think the character level stuff may need to run in a separate thread, probably using select.
+ //
+ //	I also need to support multiple 6pack ports.
+
+ // ?? Do we add this as a backend to KISS driver or a separate Driver. KISS Driver is already quite messy. Not decided yet.
+
+ // ?? If using serial/real TNC we need to be able to interleave control and data bytes, but I think with TCP/QtSM it won't be necessary
+ // ?? Also a don't see any point in running multiple copies of QtSM on one port, but maybe should treat the QtSM channels as
+ //	multidropped ports for scheduling (?? only if on same radio ??)
+
+ //	?? I think it needs to look like a KISS (L2) driver but will need a transmit scheduler level to do DCD/CSMA/PTT processing,
+ //	ideally with an interlock to other drivers on same port. This needs some thought with QtSM KISS with multiple modems on one channel
