- *		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.
- *		This method clears the way to implement other kiss protocols
- *		like mkiss smack g8bpq ..... so far only mkiss is implemented.

- *	History
- *	Jonathan (G4KLX)	Fixed to match Linux networking changes - 2.1.15.
- *	Matthias (DG2FEF)       Added support for FlexNet CRC (on special request)
- *                              Fixed bug in ax25_close(): dev_lock_wait() was
- *                              called twice, causing a deadlock.
- *	Jeroen (PE1RXQ)		Removed old MKISS_MAGIC stuff and calls to
- *				MOD_*_USE_COUNT
- *				Remove cli() and fix rtnl lock usage.
