System:NetBSD perdition.linnaean.org 1.5.1_ALPHA NetBSD 1.5.1_ALPHA (NEURALGIA) #93: Fri Feb 16 17:24:13 EST 2001     root@perdition.linnaean.org:/usr/src/sys/arch/i386/compile/NEURALGIA i386 unknown
Architecture: i386

>Description:
    NetBSD 1.5.1 has vlan support, but no code in /etc/rc.d to allow a
simple config file for it.

>How-To-Repeat:
    Install NetBSD 1.5.1.  Be a vlan junky.

>Fix:

    rc.d file appended (as diff).  Potentially rewrite rc.d/network
rather than using BEFORE.

    An example /etc/vlan.conf would look like:

vlan0	fxp0	42
