Ath9k with a AR5416 AR5133 card bad performance trunk

Description

I get very bad and erratic performance/throughput with an AR5416 AR5133 card using the ath9k driver.
This started when the "560-ath9k_rx_error_handling.patch" arrived in trunk. If I revert those changes, the throughput is normal again.(The same goes to the latest compat-wireless on a x86 in AP-mode)

Tested with a new build today, this time with an AR9280 card as AP(in RSPro).
Tried with 2 different clients, AR5418 and 5300AGN. Both clients have bad performance. (0.2 to 2-3MB/sec maybe)
This is with HT modes, seems ok not using HT.
Reverted the rx-error patch, and speed is up to over 10MB/sec again.

Some output from openwrt with a AR5416 at ht40
