| * ath9k: Fix tx throughput drops for AR9003 chips with AES encryptionRajkumar Manoharan2011-07-05
| | | | | | | | | | | | | | | | | | | | | | While sending aggregated frames in AES, the AR5416 chips required additional padding b/w subframes. This workaround is not needed for edma (AR9003 family) chips. With this patch ~4Mbps thoughput improvement was observed in clear environment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ad-hoc mode, beacon timers are configured differently compared to AP mode, and (depending on the scenario) can vary enough to make the beacon tasklet not detect slot 0 based on the TSF. Since staggered beacons are not (and cannot be) used in ad-hoc mode, it makes more sense to just hardcode slot 0 here, avoiding unnecessary TSF reads and calculations.

In ath9k we queue a work in ath9k_flush which we expect to be cancelled in the drv_stop call back. during suspend process mac80211 calls drv_stop only when the interface count(local->count) is non-zero. unfortunately when the network manager is enabled, drv_flush is called while drv_stop is not called as local->count reaches '0'. So fix this by simply checking for the device presence in the drv_flush call back in the driver before queueing work or anything else. this patch fixes the following WARNING Call Trace: [<c014c6e2>] warn_slowpath_common+0x72/0xa0 [<fc133f99>] ? ieee80211_can_queue_work+0x39/0x50 [mac80211] [<fc133f99>] ? ieee80211_can_queue_work+0x39/0x50 [mac80211] [<c014c75b>] warn_slowpath_fmt+0x2b/0x30 [<fc133f99>] ieee80211_can_queue_work+0x39/0x50 [mac80211] [<fc134ed1>] ieee80211_queue_delayed_work+0x21/0x50 [mac80211] [<fc1e5b22>] ath_tx_complete_poll_work+0xb2/0x100 [ath9k] [<c016399e>] run_workqueue+0x8e/0x150 [<fc1e5a70>] ? ath_tx_complete_poll_work+0x0/0x100 [ath9k] [<c0163ae4>] worker_thread+0x84/0xe0 [<c0167a60>] ? autoremove_wake_function+0x0/0x50 [<c0163a60>] ? worker_thread+0x0/0xe0 [<c01677d4>] kthread+0x74/0x80 [<c0167760>] ? kthread+0x0/0x80 [<c0104087>] kernel_thread_helper+0x7/0x10 ---[ end trace 2aff81010df9215b ]--- Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: Mohammed Shafi Shajakhan <mshajakhan@atheros.com> Signed-off-by: John W.
