3.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Stanislaw Gruszka <sgruszka@xxxxxxxxxx> commit dd9c46408fdc07098333655ff27edf8cac8d9fcf upstream. Jake reported that since commit 1672c0e31917f49d31d30d79067103432bc20cc7 "mac80211: start auth/assoc timeout on frame status", he is unable to connect to his AP, which is configured to use passive channel. After switch to passive channel 4965 firmware drops any TX packet until it receives beacon. Before commit 1672c0e3 we waited on channel and retransmit packet after 200ms, that makes we receive beacon on the meantime and association process succeed. New mac80211 behaviour cause that any ASSOC frame fail immediately on iwl4965 and we can not associate. This patch restore old mac80211 behaviour for iwl4965, by removing IEEE80211_HW_REPORTS_TX_ACK_STATUS feature. This feature will be added again to iwl4965 driver, when different, more complex workaround for this firmware issue, will be added to the driver.
