ath9k: disable unnecessary PHY error reporting
commit ac06697c79bad09e44a8b1d52104014016fb90de upstream. PHY errors relevant for ANI are always tracked by hardware counters, the bits that allow them to pass through the rx filter are independent of that. Enabling PHY errors in the rx filter often creates lots of useless DMA traffic and might be responsible for some of the rx dma stop failure warnings.
