iw wlan0 set txpower ...does not work using rt2x00 drivers

[Sourav]

Hi All,
I am using rt2x00 drivers for RT3072 chipset.......for changing tx 
power, I am issuing "iw wlan0 set txpower fixed <value>".....The command 
succeeds(no error from command line).
However the driver is not setting the value of the txpower....can you 
explain the logic of tx power setting by the driver and how to verify 
the change in txpower?

Warm Regards,
Sourav

This is chanctx issue, tx power setting does not work at present for drivers
that do not use chanctx. I'm looking for proper fix for this problem ...
