FreeBSD 8.0 and wlan changes

[Torfinn Ingolfsen]

This one had me stopped for a while, before figuring it out. Documented
here in case someone else stumbles across it.

In FreeBSD 7.x (and older) I used this to configure wireless i
/etc/rc.conf:
ifconfig_iwn0="WPA DHCP"

But that ones doesnt work in FreeBSD 8, for some reason.
In FreeBSD 8.0-RC2 I now have:
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA DHCP"

and that works.
There is both iwn0 and wlan0 interface now:
root@testhost-1# ifconfig iwn0
iwn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290
ether 00:1f:3b:47:b1:5b
media: IEEE 802.11 Wireless Ethernet autoselect mode 11g
status: associated
root@testhost-1# ifconfig wlan0
wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

I don't know why this change was done.

FreeBSD 8.x has support for virtual access points. You can now create any
number of virtual access points (presumably "within reason") on top of one
physical radio.

If you are running a station, this doesn't affect you, other than the fact
that you need to create a wlan interface on top of your physical interface.
