>Description:
	When entering "ifconfig eon0 iso 49" the system panics.
	The 49 is just the beginning of an address, anything makes it barf.
	The system (kernel) is configured with ISO and all was working
	until the interface list changed. (see remainder of conversion
	in sys/netiso/tuba_usrreq.c CIRCLE <-> LIST bug)

	The console shows:
	vm_fault(f8784800,0,3,0)->1
	kernel: page fault trap code, code = 0
	stopped at _iso_control + 0x100: movel %exb,0(%eax)

	trace back of stack shows the "normal" way. i.e.
	_iso_control called by _cltp_usrreq etc..
>How-To-Repeat:
	ifconfig eon0 iso 49 as command
>Fix:
	unknown. (yet) (guess is: fix static initialisation)
