Hi all, there is some kind of regression with setting transmit power, hardware is warious
ar9280 cards, all work as sould with compat-wireless-3.6 and compat-drivers-2013-02-13, i 
have modified regulatory database:

iw reg get
country RU:
     (2402 - 2494 @ 40), (24, 23)
     (5030 - 5835 @ 40), (24, 23)

with compat-wireless-3.6 and compat-drivers-2013-02-13 i can change txpower in this rules,
iw list show channels and it's power according to database rules:

                 Frequencies:
                         * 2412 MHz [1] (23.0 dBm)
                         * 2417 MHz [2] (23.0 dBm)
                         * 2422 MHz [3] (23.0 dBm)
                         * 2427 MHz [4] (23.0 dBm)
                         * 2432 MHz [5] (23.0 dBm)
                         * 2437 MHz [6] (23.0 dBm)
                         * 2442 MHz [7] (23.0 dBm)
                         * 2447 MHz [8] (23.0 dBm)
                         * 2452 MHz [9] (23.0 dBm)
                         * 2457 MHz [10] (23.0 dBm)
                         * 2462 MHz [11] (23.0 dBm)
                         * 2467 MHz [12] (23.0 dBm)
                         * 2472 MHz [13] (23.0 dBm)
                         * 2484 MHz [14] (23.0 dBm)

but with compat-drivers 3.7.6 and 3.8-rc7 i cannot set power level, 
iw phy phy0 set txpower fixed 10/limit 10/iw dev dev0/etc give same 
error - command failed: Operation not supported (-95), and iw list 
give strange output like this:

                 Frequencies:
                         * 2412 MHz [1] (20.0 dBm)
                         * 2417 MHz [2] (21.0 dBm)
                         * 2422 MHz [3] (21.0 dBm)
                         * 2427 MHz [4] (21.0 dBm)
                         * 2432 MHz [5] (21.0 dBm)
                         * 2437 MHz [6] (21.0 dBm)
                         * 2442 MHz [7] (21.0 dBm)
                         * 2447 MHz [8] (21.0 dBm)
                         * 2452 MHz [9] (21.0 dBm)
                         * 2457 MHz [10] (21.0 dBm)
                         * 2462 MHz [11] (20.0 dBm)
                         * 2467 MHz [12] (23.0 dBm)
                         * 2472 MHz [13] (23.0 dBm)
 		        * 2484 MHz [14] (23.0 dBm)

and channel levels different on different cards.
