>Description:
	/sbin/route does not handle IPv6 syntax if built with -DSMALL -DINET6
	(it's OK though if SMALL is *not* defined) because a few INET6 portions
	of code in src/sbin/route/route.c and src/sbin/route/show.c
	are still hidden by SMALL (the fix is short and given at the end).
>How-To-Repeat:
	Use crunchgen to build route.
	Check that the *standard* /sbin/route is working ok with IPv6 syntax :
	tri# route add -inet6 default ba.lan
	add net default: gateway ba.lan
	tri# route delete -inet6 default ba.lan
	delete net default: gateway ba.lan
	Now try the crunched binary :
	tri# ./triram route delete -inet6 default ba.lan
	writing to routing socket: No such process
	tri$ ./triram route show
	Routing tables

	Internet:
	Destination       Gateway            Flags 
	default           192.168.1.1        UG     
	loopback          127.0.0.1          UGR    
	localhost         127.0.0.1          UH     
	192.168.1.0       link#1             U      
	ba.lan            00:00:e8:d9:af:51  UH

>Fix:
	Patches for both 1.6.1 and -current users are given here.
	cd /usr/src/sbin/route

	For NetBSD-1.6.1 users :

	Patch route.c,v 1.54.2.4 2003/01/26 09:40:35 jmc with :
	patch route.c <<EOF
	1234a
	#ifndef SMALL
	.
	1189d
	744a
	#ifndef SMALL
	.
	698d
	586a
	#ifndef SMALL
	.
	540d
	EOF

	Patch show.c,v 1.19 2001/10/24 16:05:07 atatat with :
	patch show.c <<EOF
	295a
	#ifndef SMALL
	.
	286d
	240a
	#ifndef SMALL
	.
	235d
	EOF

	---

	For NetBSD-current users :

	Patch route.c,v 1.70 2003/10/01 06:24:19 itojun with :
	patch route.c <<EOF
	2012a
	#ifndef SMALL

	739a
	#ifndef SMALL
	.
	695d
	581a
	#ifndef SMALL
	.
	537d
	EOF

	Patch show.c,v 1.21 2003/08/07 10:04:39 agc with :
	patch show.c <<EOF
	291a
	#ifndef SMALL
	.
	282d
	236a
	#ifndef SMALL
	.
	231d
	EOF

	I haven't built nor tested the patch for -current, but with 1.6.1 it
	works as expected (i.e. just like the standard route) :
	tri# ./triram route add -inet6 default ba.lan
	add net default: gateway ba.lan
	tri# ./triram route delete -inet6 default ba.lan
	delete net default: gateway ba.lan
	tri$ ./triram route show
	Routing tables

	Destination       Gateway            Flags

	loopback          127.0.0.1          UGR    
	localhost         127.0.0.1          UH

	tri.lan           00:80:ad:91:a4:10  UH     
	fe80::            localhost          UGR    
	fe80::%ne0        link#1             U      
	fe80::%lo0        fe80::1%lo0        U      
	ff01::            localhost          U      
	ff02::%ne0        link#1             U      
	ff02::%lo0        fe80::1%lo0        U      

	And of course it also works form my diskless kernel.

	P.S. I'm using 3fff:: instead of fec0:: cause I haven't found yet why
	my hosts.allow/inetd is refusing intranet connections although I have
	ip6sitelocal=YES in rc.conf. Anyway I'm behind an IPv6-disabled ISP...
