I tested your patch on my AP (rt2860 / pci) with an AR9285 STA using
netperf / 802.11n / 2.4 GHz / 40 MHz. I experienced 2 times reproducible
3 MBit less TX and 1 MBit less RX.


BTW:
I'm seeing some other entries since a few days (unfortunately I cannot
say which patch caused them exactly as they come up sporadically):

If they came up once, RX is very bad (less then half). To get rid of
this performance issue, I have to reload the module.

My source is:
compat-wireless-2012-02-02 with limit tx-queues-length for pci and
actual fix random stalls.
