* carl9170: fix WARN_ON triggered by Broadcom HT STAsChristian Lamparter2010-09-281-1/+1
| | | | | | | | | | | | Broadcom's Windows driver for the 4313 advertises an ampdu density of 7 => 16 us. The AR9170 MAC on the other hand only supports densities up to 8 us. This patch removes the noisy WARN_ON, because there is nothing we can do about it. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* carl9170: fix tx_ampdu_upload counterChristian Lamparter2010-09-281-1/+14
| | | | | | | | | | | | | tx_ampdu_upload was not decreased when an a-MPDU frame had to be kicked out from the tx_pending queues. This broke ampdu aggregation, because the scheduler waits until tx_ampdu_upload drops to zero, before making the next aggregate.

* carl9170: remove lost-frame workaroundChristian Lamparter2010-09-283-40/+2
| | | | | | | | | | | | | | | | This patch removes some cruft, which survived the RFC review phase. Originally, carl9170_tx_ampdu_queue erroneously dropped a lot of frames. As a result the ampdu scheduler bogged down quite frequently and the affected BA session timed out. However this bug has been fixed and the WA and its debugfs counter is no longer useful.

* mac80211/ath9k: Support AMPDU with multiple VIFs.Ben Greear2010-09-272-3/+6
| | | | | | | | | | | | | | | | The old ieee80211_find_sta_by_hw method didn't properly find VIFS when there was more than one per AP. This caused AMPDU logic in ath9k to get the wrong VIF when trying to account for transmitted SKBs. This patch changes ieee80211_find_sta_by_hw to take a localaddr argument to distinguish between VIFs with the same AP but different local addresses. The method name is changed to ieee80211_find_sta_by_ifaddr. Signed-off-by: Ben Greear <greearb@candelatech.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| | | | | | | | | | | | | | | The "basic_rate" module option is not implemented correctly. If the rate was set to zero it was supposed to set it to "basic_rate | 0x80". Unfortunately the check to see if what zero was wrong and it checked "!ai->config.rates" (which is always false) instead of "!ai->config.rates[i]". This option was just used for development and it wasn't documented anywhere. Instead of fixing it, we can just remove it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tid aggregation cleanup is a bit fragile, as it discards failed subframes in some places, and retransmits them in others. This could block the cleanup of an existing aggregation session, if a retransmission for a tid is issued, yet the tid is never scheduled again because of the cleanup state. Fix this by getting rid of as many subframes as possible, as early as possible, and immediately transmitting pending subframes as regular HT frames instead of waiting for the cleanup to complete. Drop all pending subframes while keeping track of the Block ACK window during aggregate tx completion to prevent sending out stale subframes, which could confuse the receiver side.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we return a TX descriptor to the pool of available descriptors, while a queues TXDP still points to it we could potentially run into all sorts of troube. It has been suggested that there is hardware which can set the descriptors done bit before it reads ds_link and moves on to the next descriptor. While the documentation says this is not true for newer chipsets (the descriptor contents are copied to some internal memory), we don't know about older hardware. To be safe, we always keep the last descriptor in the queue, and avoid dangling TXDP pointers. Unfortunately this does not fully resolve the problem - queues still get stuck! This is similar to what ath9k does. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | Since we do not know any better solution to the problem that TX queues can get stuck, this adds a timer-based watchdog, which will check for stuck queues and reset the hardware if necessary.

| | | | | | | | | | | | | | | | | | | | It does not make sense to stop queues for NF calibration. This will not stop transmissions from the card, if there are queued packets. If we run out of TX buffers we need to stop all queues, not only one. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | ath5k: Use four hardware queuesBruno Randolf2010-09-212-7/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prepare ath5k for WME by using four hardware queues. The way we set up our queues matches the mac80211 queue priority 1:1, so we don't have to do any mapping for queue numbers. Every queue uses 50 of the total 200 available transmit buffers, so the DMA memory usage does not increase with this patch, but it might be good to fine-tune the number of buffers per queue later (depending on the CPU speed and load, and the speed of the medium access, it might not be big enough).

* | ath5k: reorder base.c to remove fwd declsBob Copeland2010-09-211-898/+764
| | | | | | | | | | | | | | | | | | | | | | This change reorganizes the main ath5k file in order to re-group related functions and remove most of the forward declarations (from 61 down to 3). This is, unfortunately, a lot of churn, but there should be no functional changes.
