I just turned off pmtu discovery and my kernel just panic()ed. I'm running

        NetBSD 1.6I (NUTCRACKER) #49: Sun Oct 20 19:26:43 CEST 2002

the bad thing seems to happen since 

	(gdb) p ip_mtudisc_timeout_q
	$1 = (struct rttimer_queue *) 0x0


shouldn't the pmtu code avoid being run when its turned off ?

Love
