3.5.7.15 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Sujith Manoharan <[email protected]> commit 531671cb17af07281e6f28c1425f754346e65c41 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. Signed-off-by: Sujith Manoharan <[email protected]> Signed-off-by: John W.
