iw can‘t run in WRT54GS v3 and WRT350n v2 normally

[anonymous]

In the iw home page (​http://wireless.kernel.org/en/users/Documentation/iw), it shows many usage examples, such as:

Listening to events
iw event

When debugging, it can be useful to see the auth/assoc/deauth/disassoc frames, use :
iw event -f

To enable power save by default you can use:
iw dev wlan0 set power_save on

However，these can't be executed normally in my OpenWRT devices(Linksys WRT54GS v3 and WRT350n v2).I have made some related tests:

root@OpenWrt:~# iw event
wlan0: new station 00:26:68:5c:9f:22
wlan0: new station 00:26:68:5c:9f:22
wlan0: new station 00:26:68:5c:9f:22

root@OpenWrt:~# iw event -f 
wlan0: new station 00:26:68:5c:9f:22
wlan0: new station 00:26:68:5c:9f:22
wlan0: new station 00:26:68:5c:9f:22

(Didn't show any other more info to me ,such as auth/assoc/deauth/disassoc frames!! )

root@OpenWrt:~# iw dev wlan0 get power_save 
Power save: off

root@OpenWrt:~# iw dev wlan0 set power_save on
command failed: Operation not supported (-95)

(Operation not supported !!)

root@OpenWrt:~# iw --version
iw version 0.9.21

%%%%%%%%%%%%

Then I download iw-0.9.21 source code from its home page, and read it. I found these functions seems to have been implemented. So it looks like OpenWRT didn't support iw fully in my thought.

It is normal that not all drivers implement all operations.
