* mac80211/iwlwifi: move virtual A-MDPU queue bookkeeping to iwlwifiJohannes Berg2009-03-27
| | | | | | | | | | | | | | | | | | This patch removes all the virtual A-MPDU-queue bookkeeping from mac80211. Curiously, iwlwifi already does its own bookkeeping, so it doesn't require much changes except where it needs to handle starting and stopping the queues in mac80211. To handle the queue stop/wake properly, we rewrite the software queue number for aggregation frames and internally to iwlwifi keep track of the queues that map into the same AC queue, and only talk to mac80211 about the AC queue. The implementation requires calling two new functions, iwl_stop_queue and iwl_wake_queue instead of the mac80211 counterparts.

* mac80211: fix aggregation to not require queue stopJohannes Berg2009-03-27
| | | | | | | | | | | | | | | | | | | Instead of stopping the entire AC queue when enabling aggregation (which was only done for hardware with aggregation queues) buffer the packets for each station, and release them to the pending skb queue once aggregation is turned on successfully. We get a little more code, but it becomes conceptually simpler and we can remove the entire virtual queue mechanism from mac80211 in a follow-up patch. This changes how mac80211 behaves towards drivers that support aggregation but have no hardware queues -- those drivers will now not be handed packets while the aggregation session is being established, but only after it has been fully established.

* mac80211: rework the pending packets codeJohannes Berg2009-03-27
| | | | | | | | | | | | The pending packets code is quite incomprehensible, uses memory barriers nobody really understands, etc. This patch reworks it entirely, using the queue spinlock, proper stop bits and the skb queues themselves to indicate whether packets are pending or not (rather than a separate variable like before).

* mac80211: split IBSS/managed codeJohannes Berg2009-02-27
| | | | | | | | | | | | | | | | | This patch splits out the ibss code and data from managed (station) mode. The reason to do this is to better separate the state machines, and have the code be contained better so it gets easier to determine what exactly a given change will affect, that in turn makes it easier to understand. This is quite some churn, especially because I split sdata->u.sta into sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that way. I've also shuffled around some code -- null function sending is only applicable to managed interfaces so put that into that file, some other functions are needed from various places so put them into util, and also rearranged the prototypes in ieee80211_i.h accordingly.

* mac80211: fix aggregation for hardware with ampdu queuesJohannes Berg2009-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware with AMPDU queues currently has broken aggregation. This patch fixes it by making all A-MPDUs go over the regular AC queues, but keeping track of the hardware queues in mac80211. As a first rough version, it actually stops the AC queue for extended periods of time, which can be removed by adding buffering internal to mac80211, but is currently not a huge problem because people rarely use multiple TIDs that are in the same AC (and iwlwifi currently doesn't operate as AP). This is a short-term fix, my current medium-term plan, which I hope to execute soon as well, but am not sure can finish before .30, looks like this: 1) rework the internal queuing layer in mac80211 that we use for fragments if the driver stopped queue in the middle of a fragmented frame to be able to queue more frames at once (rather than just a single frame with its fragments) 2) instead of stopping the entire AC queue, queue up the frames in a per-station/per-TID queue during aggregation session initiation, when the session has come up take all those frames and put them onto the queue from 1) 3) push the ampdu queue layer abstraction this patch introduces in mac80211 into the driver, and remove the virtual queue stuff from mac80211 again This plan will probably also affect ath9k in that mac80211 queues the frames instead of passing them down, even when there are no ampdu queues.

* mac80211: change workqueue back to non-freezeableBob Copeland2009-01-29
| | | | | | | | | | | | | | | | | | | | | "mac80211: make workqueue freezable" made the mac80211 workqueue freezeable to prevent us from doing any work after the driver went away. This was fine before mac80211 had any suspend support. However, now we want to flush this workqueue in suspend(). Because the thread for a freezeable workqueue is stopped before the device class suspend() is called, flush_workqueue() will hang in the suspend-to-disk case. Converting it back to a non-freezeable queue will keep suspend from hanging. Moreover, since we flush the workqueue under RTNL and userspace is stopped, there won't be any new work in the workqueue until after resume. Thus we still don't have to worry about pinging the AP without hardware. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: implement dynamic power saveKalle Valo2008-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements dynamic power save for mac80211. Basically it means enabling power save mode after an idle period. Implementing it dynamically gives a good compromise of low power consumption and low latency. Some hardware have support for this in firmware, but some require the host to do it. The dynamic power save is implemented by adding an timeout to ieee80211_subif_start_xmit(). The timeout can be enabled from userspace with Wireless Extensions. For example, the command below enables the dynamic power save and sets the time timeout to 500 ms: iwconfig wlan0 power timeout 500m Power save now only works with devices which handle power save in firmware. It's also disabled by default and the heuristics when and how to enable is considered as a policy decision and will be left for the userspace to handle. In case the firmware has support for this, drivers can disable this feature with IEEE80211_HW_NO_STACK_DYNAMIC_PS. Big thanks to Johannes Berg for the help with the design and code.

* mac80211: warn on some invalid vlan operationsJohannes Berg2008-09-15
| | | | | | | | | These should never happen, but better warn about them than crashing a driver, the fact that they never happen is rather subtle throughout mac80211. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: move regular interface handlingJohannes Berg2008-09-15
| | | | | | | | Move the code to handle regular interfaces out of main.c and into iface.c, keep only the master interface stuff in main.c. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: use nl80211 interface typesJohannes Berg2008-09-15
| | | | | | | | | | There's really no reason for mac80211 to be using its own interface type defines. Use the nl80211 types and simplify the configuration code a bit: there's no need to translate them any more now. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
