* iwlagn: 6050 ops should be used;Wey-Yi Guy2010-10-14

* iwlwifi: clean up some beacon handlingJohannes Berg2010-10-14
| | | | | | | | | | | | | | | | | | There's no need to check for NULL before calling dev_kfree_skb() since it is valid to call it on NULL -- it becomes a no-op. There's also no need to initialise the beacon_skb variable to NULL just after the memory it is in has been kzalloc'ed. Some minor whitespace cleanups, and a lock assertion in a function that needs the mutex (to access the beacon_skb var) complete the patch.

* iwlwifi: allow probe-after-rx on 2.4 GHzJohannes Berg2010-10-14
| | | | | | | | | | | | | | | | | There are two passive 2.4 GHz channels: 12 and 13. If you have a hidden SSID on those, you will not be able to connect to it because we don't send out probe requests there. We can allow this by using the firmware's probe-after-rx functionality on those channels as well.

* | rt2x00: Move watchdog work to kernel work_queueIvo van Doorn2010-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The watchdog function must run on a work_queue which is independent of any other work inside rt2x00. The main reasons, being that a broken work on the mac80211 work_queue can otherwise prevent the watchdog to run (while in fact the watchdog could fix the issue). And on the other hand because the watchdog relies on the completion of the completion handlers for RX/TX which for the USB case, occur on the mac80211 workqueue. This fixes some "Queue %d failed to flush" errors, which were caused by the watchdog function waiting on the completion handler which was scheduled to run right after the watchdog.

* | rt2x00: Simplify Queue function argumentsIvo van Doorn2010-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of functions accept a struct rt2x00_dev combined with either a struct queue_entry or struct data_queue argument. This can be simplified by only passing on the queue/entry argument. In cases where rt2x00_dev and a sk_buff are send together, we can send the queue_entry instead. rt2x00usb_alloc_urb and rt2x00usb_free_urb have a bit of vague naming. Instead they allocate all the data which belongs to a rt2x00 data queue entry.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch attempts to ensure that ath9k's built-in rate control algorithm does not rely on the value of the ampdu_len and ampdu_ack_len tx status fields unless the IEEE80211_TX_STAT_AMPDU flag is set.

* | ath9k: A-MPDU rate control info fixBjörn Smedman2010-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the following problems with the rate control feedback generated by ath9k for A-MPDU frames: 1. Rate control feedback is carried on the first frame of an aggregate that is either ACKed, or has execeeded the software retry count and is considered failed. However, ath9k would incorrectly assume the aggregate had the length 1 if one of these conditions did not apply to the first frame of the aggregate, but instead a later frame. This fix therefor copies the bf_nframes field of the buffer in the same manner as the rates field of the tx status. 2. Sometimes the ampdu_len and ampdu_ack_len fields of the tx status was left uninitialized eventhough the IEEE80211_TX_STAT_AMPDU flag was set. This is now avoid by setting flag and fields in the same place. 3. Even if a frame has been selected for aggregation by mac80211 and marked with the IEEE80211_TX_CTL_AMPDU flag it can sometimes happen that ath9k transmits the frame without aggregation. In these cases the ampdu_ack_len field could be incorrectly computed because the nbad parameter to ath_tx_rc_status was incorrect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | wl1271 driver is under heavy development but on the other hand the older wl1251 driver is currently considered more as a legacy driver. To make it easier to develop wl1271 features move wl1251 to it's own directory, drivers/net/wireless/wl1251. There are no functional changes, only moving of files.
