+Subject: ath9k: Disable PowerSave by default
+
+commit 73c79617596b89a3693ff0d89d42bcd5ddedcf15 upstream.
+
+Almost all the DMA issues which have plagued ath9k (in station mode)
+for years are related to PS. Disabling PS usually "fixes" the user's
+connection stablility. Reports of DMA problems are still trickling in
+and are sitting in the kernel bugzilla. Until the PS code in ath9k is
+given a thorough review, disbale it by default. The slight increase
+in chip power consumption is a small price to pay for improved link
+stability.
