16 * like mkiss smack g8bpq ..... so far only mkiss is implemented.

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