>Description:

Using a machine that is a router with several interfaces, one of which is
a wireless card, the pccard interface is not setup as an ipv6 capable
interface. Basically, pccards are only allowed as endhosts.

>How-To-Repeat:

Turn on ipv6_gateway_enable in /etc/rc.conf and watch you wavelan card not
get setup

>Fix:

I hacked up rc.network6 and pccard_ether so that the interface(s) that will
be attempted to be brought up are passed to the function. This allows
network6_interface_setup() to be reused and called by /etc/pccard_ether
Anyway, here's the patch:
