Subject: iw set fixed bitrate doesn't commit at 802.11n mode

Hello all.

I'm working on 5 GHz band, Microtik R52n-M card and when forcing
bitrate, it doesn't work for .11n mode executing the following comands:
- iw dev wlan0 set noack_map 0x0009
- iw dev wlan0 set bitrates ht-mcs-5 10

No error is thrown but PHY bitrate remains at 6.0 Mbit/s.
After that, I execute comand
- iw dev wlan0 set bitrates legacy-5 54
and bitrate goes up to 54 Mbit/s (iperf UDP goes from 5.5 Mbit/s to
31.5Mbit/s)

Doing "iw dev wlan0 set bitrates mcs-5 10" bitrate falls back to 6 Mbit/s.

Tested on Ubuntu version 14.04.02 LTS x64, AP-STA mode.

Thanks.
