Fluctuating rate mask

Description

Hi all,

I'm working with a TP-LINK archer c5 running CHAOS CALMER (15.05, r46767).
After trying to apply the rate mask on the 2.4 GHz interface, I noticed some fluctuation on the values, specifically on the tx bitrate.

Best Regards,
Pedro

There seems to be a problem on fixing the rate parameter on 802.11n.
From Dmesg output after setting the rate mask:
