dmesg output afer setting debug to 0x3fff


there is no error message when doing "iwconfig eth1 txpower off".
attached is the dmesg output afer setting debug to 0x3fff.
the steps i did are:
1, % ./unload
2, % dmesg -c
3, % ./load debug=0x3fff
4, % iwconfig
   i can see txpower is default to 20dBm.
5, % iwconfig eth1 txpower off
6, % iwconfig
i can see txpower is still 20dBm.

Reopen the bug.

Looks like it just isn't reporting the power disabled bit to the wireless tools.
 You can verify that the power is being shut off via:

cat /sys/bus/pci/drivers/ipw2200/*/rf_kill 

I've put in a fix for 0.18 that will report the state of the radio power to user
space.
