Description

Hello there.

I'm working on 5 GHz band, Microtik R52n-M card and when forcing bitrate, it doesn't work for .11n mode doing the following:

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)

There is a problem on fixing bitrate in 802.11n, in mode 802.11g and 802.11a works good.

Tested at r44510.

Thanks.
