From: Stephen Hemminger @ 2003-08-05 22:43 UTC (permalink / raw)
  To: Henner Eisen, David S. Miller, linux-x25, netdev

Convert X.25 async driver to have dynamic net_device's.
This driver is a lot like SLIP so the code changes were similar.  
	- Added similar locking to SLIP
	- replaced code that snooped for MTU changes with the
 	  net_device change mtu callback.
	- cleaned up the statistics by using the net_device_stats structure.

Patch is against 2.6.0-test2.

Not sure if anyone ever uses this.  I tested by bringing up an x.25 async
line using a modified version of slattach.
