2012-03-06iwlwifi: remove shared lockJohannes Berg
Some data doesn't need protection, some of the lock places are simply useless, and some data can be protected with the mutex instead. Thus the shared lock can be removed by making those changes.

2012-03-06iwlwifi: introduce statistics lockJohannes Berg
The statistics are currently only half-heartedly locked against concurrent reading & modification so introduce a lock to really protect them.

2012-03-06iwlwifi: make sta lock private & BH lockJohannes Berg
Now that the transport has its own locking, there's no need to have the sta_lock in the shared data. Also, it can be a BH lock as it's not used from IRQ handlers.

2012-03-06iwlwifi: introduce per-queue locksJohannes Berg
Instead of (ab)using the sta_lock, make the transport layer lock its own TX queue data structures with a lock per queue. This also unifies with the cmd queue lock.

2012-03-06iwlwifi: build some station commands directlyJohannes Berg
In the powersave related functions we only need to set a few parameters for the station command and can otherwise leave it blank -- there's no need to copy it from the database. This allows us to not use the sta lock here. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-03-06iwlwifi: simplify code in iwlagn_key_sta_idJohannes Berg
Simplify the code by returning directly in the error case and replacing the switch/if with a single if statement. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-03-06iwlwifi: reduce sta_lock hold time in TXJohannes Berg
When we TX, we hold the sta_lock for a long time, a lot of which isn't needed. Reduce the time we hold the lock. Note that this doesn't really change anything as the code is already under the other spinlock, but it makes the code easier to read.

2012-03-06iwlwifi: move iwl_clear_driver_stations to userJohannes Berg

2012-03-06iwlwifi: always monitor for stuck queuesJohannes Berg
If we only monitor while associated, the following can happen: - we're associated, and the queue stuck check runs, setting the queue "touch" time to X - we disassociate, stopping the monitoring, which leaves the time set to X - almost 2s later, we associate, and enqueue a frame - before the frame is transmitted, we monitor for stuck queues, and find the time set to X, although it is now later than X + 2000ms, so we decide that the queue is stuck and erroneously restart the device It happens more with P2P because there we can go between associated/unassociated frequently.

2012-02-29mac80211: handle non-bufferable MMPDUs correctlyJohannes Berg
This renames the IEEE80211_TX_CTL_POLL_RESPONSE TX flag to IEEE80211_TX_CTL_NO_PS_BUFFER and also uses it for non-bufferable MMPDUs (all MMPDUs but deauth, disassoc and action frames.) Previously, mac80211 would let the MMPDU through but not set the flag so drivers supporting some hardware aids for avoiding the PS races would then reject the frame.

2012-02-27iwlwifi: move uCode flags handling to op_modeJohannes Berg
The uCode flags modification is op_mode dependent since the P2P config is an op-mode config. This also fixes P2P enabling: due to the uCode loading code shuffle moving the SKU check before the EEPROM was read it was always false and would always disable PAN/P2P.

2012-02-27iwlwifi: move content of iwl_probe to post fetch_fwEmmanuel Grumbach
This will allow to have different behavior depending on the fw. Different fw APIs require completely different implementation of the mac80211 APIs. Each of these implementations is called an op_mode.

2012-02-21iwlwifi: fix key removalJohannes Berg
When trying to remove a key, we always send key flags just setting the key type, not including the multicast flag and the key ID. As a result, whenever any key was removed, the unicast key 0 would be removed, causing a complete connection loss after the second rekey (the first doesn't cause a key removal). Fix the key removal code to include the key ID and multicast flag, thus removing the correct key.
