Description Mike Bristow 1999-12-06 19:20:00 UTC 
ifconfig will dump core when run with certain arguments; this is when
the struct afswtch contains a NULL function pointer which gets called.

Fix: The following patch will fix the core dump by making ifconfig notice a
NULL function pointer and exit.  It applies to FreeBSD-STABLE; I
haven't checked FreeBSD-CURRENT (other than confirming that the
behaviour is identical). 
How-To-Repeat: 
	/sbin/ifconfig foo0 ether 66:c0:4f:60:49:e1
	(with some value of foo that exists on the system)
