2009-06-10ath5k: minor rfkill cleanupBob Copeland6-26/+8
Always enable rfkill since the ifdefs in the code is not really worth the Kconfig option. Also fix a few code style things, and remove the usage of the ah_gpio[] array so we can remove it later.

2009-06-10ath9k: Fix tx stuck when connected to aggr disabled HT APVasanthakumar Thiagarajan1-0/+1
This patch along with my previous patch in mac80211 "Fix the way ADDBA count..", fixes hang in tx when connected to an HT AP which rejects/times out on addba req. AGGR_ADDBA_PROGRESS should be cleared in aggr state when addba negotiation is terminated due to either addba response is timed out or addba is denied by the AP. With out clearing this bit, all frames are queued onto s/w queue for getting tx'd as aggr and will never be scheduled onto hw queue.

2009-06-10ath5k: added cfg80211 based rfkill supportTobias Doerffel7-17/+163
This patch introduces initial rfkill support for the ath5k driver based on rfkill support in the cfg80211 framework. All rfkill related code is separated into newly created rfkill.c. Changes to existing code are minimal: * added a new data structure ath5k_rfkill to the ath5k_softc structure * inserted calls to HW rfkill init/deinit routines * ath5k_intr() has been extended to handle AR5K_INT_GPIO interrupts Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-06-10ar9170: xmit code revampChristian Lamparter5-260/+550
This patch is a back-port from aggregation testing code. In the past, we didn't limit the amount of active tx urbs. However, ar9170 only has a limited buffer reserved for pending data frames. This wasn't much of a problem with the slower 802.11b/g. We simply stopped the full queue and moved on to something different in the mean time. But - as you guessed it - this simple approach stands in way for a decent aggregation implementation. Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W.

2009-06-03rfkill: rewriteJohannes Berg3-107/+30
This patch completely rewrites the rfkill core to address the following deficiencies: * all rfkill drivers need to implement polling where necessary rather than having one central implementation * updating the rfkill state cannot be done from arbitrary contexts, forcing drivers to use schedule_work and requiring lots of code * rfkill drivers need to keep track of soft/hard blocked internally -- the core should do this * the rfkill API has many unexpected quirks, for example being asymmetric wrt. alloc/free and register/unregister * rfkill can call back into a driver from within a function the driver called -- this is prone to deadlocks and generally should be avoided * rfkill-input pointlessly is a separate module * drivers need to #ifdef rfkill functions (unless they want to depend on or select RFKILL) -- rfkill should provide inlines that do nothing if it isn't compiled in * the rfkill structure is not opaque -- drivers need to initialise it correctly (lots of sanity checking code required) -- instead force drivers to pass the right variables to rfkill_alloc() * the documentation is hard to read because it always assumes the reader is completely clueless and contains way TOO MANY CAPS * the rfkill code needlessly uses a lot of locks and atomic operations in locked sections * fix LED trigger to actually change the LED when the radio state changes -- this wasn't done before Tested-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> [thinkpad] Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2009-06-03ath9k: Add sanity check for beacon_int in adhoc/mesh caseJouni Malinen1-0/+8
It looks like mac80211 can request the driver to start beaconing with a beacon interval of zero in some cases (at least for mesh point). This does not sound correct and something may need to be fixed in mac80211. However, taken into account the unpleasantness of getting stuck in an infinite busy loop with rtnl_lock held, let's add a quick workaround in the driver to avoid the worst symptom while someone more familiar with the mesh implementation can figure out what should be done with mac80211 as far as beacon interval configuration is concerned.

2009-05-22ath9k: Update Beacon timers based on timestamp from the APJouni Malinen3-1/+16
Some APs seem to drift away from the expected TBTT (timestamp % beacon_int_in_usec differs quite a bit from zero) which can result in us waking up way too early to receive a Beacon frame. In order to work around this, re-configure the Beacon timers after having received a Beacon frame from the AP (i.e., when we know the offset between the expected TBTT and the actual time the AP is sending out the Beacon frame).

2009-05-22ath9k: Optimize TBTT/DTIM calculation for timersJouni Malinen1-7/+21
The previous version used a simple loop to go through all Beacon frames when determining the next TBTT and DTIM count. This is not too bad for the case where the setup happens before timesync (i.e., very small TSF), but this can become very heavy operation if a short Beacon interval is used and the current TSF is large.

mac80211 does not set PM field for normal data frames, so we need to update that based on the current PS mode when using PS-Poll (timeout=0) power save mode. This allows the AP to remain in sync with our PS state. However, there is still a potential race condition between PS state changes when multiple TX queues are used and nullfunc and PS-Poll frames use different queue. That corner case may need to be handled separately by changing which queue is used either in ath9k or mac80211. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

2009-05-20ath9k: cleanup beacon parameters configurationVasanthakumar Thiagarajan2-28/+36
This patch configures the beacon timers with beacon interval and beacon period passed through vif.bss_conf. Also cache the currecnt beacon configuration which will be used to configure the beacon timers when the driver triggers it after reset.

2009-05-20ath9k: Fix PS mode operation to receive buffered broadcast/multicast framesJouni Malinen3-7/+114
The previous implementation was moving back to NETWORK SLEEP state immediately after receiving a Beacon frame. This means that we are unlikely to receive all the buffered broadcast/multicast frames that would be sent after DTIM Beacon frames. Fix this by parsing the Beacon frame and remaining awake, if needed, to receive the buffered broadcast/multicast frames. The last buffered frame will trigger the move back into NETWORK SLEEP state. If the last broadcast/multicast frame is not received properly (or if the AP fails to send it), the next Beacon frame will work as a backup trigger for returning into NETWORK SLEEP. A new debug type, PS (debug=0x800 module parameter), is added to make it easier to debug potential power save issues in the future. Currently, this is only used for the Beacon frame and buffered broadcast/multicast receiving. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

2009-05-20ath9k: Clean up RX processing a bitJouni Malinen1-26/+34
This makes use of the local fc variable in bit more places and uses a common helper macro. The part of RX process that delivers skb's to mac80211 is moved to a separate function in preparation for future changes that will need to do this from two places. The modifications here should not result in any functional changes. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-05-20cfg80211: Process regulatory max bandwidth checks for HT40Luis R. Rodriguez1-4/+6
We are not correctly listening to the regulatory max bandwidth settings. To actually make use of it we need to redesign things a bit. This patch does the work for that. We do this to so we can obey to regulatory rules accordingly for use of HT40. We end up dealing with HT40 by having two passes for each channel. The first check will see if a 20 MHz channel fits into the channel's center freq on a given frequency range. We check for a 20 MHz banwidth channel as that is the maximum an individual channel will use, at least for now. The first pass will go ahead and check if the regulatory rule for that given center of frequency allows 40 MHz bandwidths and we use this to determine whether or not the channel supports HT40 or not. So to support HT40 you'll need at a regulatory rule that allows you to use 40 MHz channels but you're channel must also be enabled and support 20 MHz by itself. The second pass is done after we do the regulatory checks over an device's supported channel list. On each channel we'll check if the control channel and the extension both: o exist o are enabled o regulatory allows 40 MHz bandwidth on its frequency range This work allows allows us to idependently check for HT40- and HT40+.
