Something incorrect in networking scripts.

Hi guys.

I have a Thinkpad r50e with a PRO/Wireless 2200BG WLAN nic - iwi device.
When I set it up in rc.conf to be called wlan0 instead of iwi0 :

ifconfig_fxp0_name="lan0"      # Change interface name from fxp0 to net0.
ifconfig_lan0=dhcp
ifconfig_iwi0_name="wlan0"
ifconfig_wlan0="inet 12.23.34.45 netmask 255.255.255.0 ssid MY_SSID"

and then create /etc/start_if_wlan0 :
iwicontrol wlan0 -d /usr/local/libdata/if_iwi -m bss
iwicontrol -i wlan0 -r
ifconfig wlan0 up

The file does not seem to be used. When I rename it to start_if_iwi0 it is not used either.
I need to manually run the lines from it.
lan0 is brought up fine with dhcp.

Cheers,
Marcin Jessa.
