Linville" Cc: linux-wireless@vger.kernel.org Subject: [PATCH 0/4] ath9k: Power save mode fixes Sender: linux-wireless-owner@vger.kernel.org List-ID: This series addresses couple of issues in power save mode operations in ath9k. The driver will now try to receive all buffered broadcast and multicast frames after DTIM beacons. In addition, the transitions between power save states are optimized in a way which should reduce both CPU use and the amount of time spent in awake state. This change seems to also improve the stability of the connection when using power save mode. There are still some remaining issues in the timeout=0 power save case ("iwconfig wlan0 power on"), but the patches here seem to make the default mode (timeout=500, "iwconfig wlan0 power timeout 500ms") behave much more nicely. -- Jouni Malinen PGP id EFC895FA
