2014-01-08ath9k_htc: properly set MAC address and BSSID maskMathy Vanhoef1-2/+3
commit 657eb17d87852c42b55c4b06d5425baa08b2ddb3 upstream. Pick the MAC address of the first virtual interface as the new hardware MAC address. Set BSSID mask according to this MAC address.

2013-05-19ath9k: fix key allocation error handling for powersave keysFelix Fietkau1-1/+5
commit 4ef69d0394cba8caa9f75d3f2e53429bfb8b3045 upstream. If no keycache slots are available, ath_key_config can return -ENOSPC. If the key index is not checked for errors, it can lead to logspam that looks like this: "ath: wiphy0: keyreset: keycache entry 228 out of range" This can cause follow-up errors if the invalid keycache index gets used for tx.

2012-07-16ath9k: Fix a WARNING on suspend/resume with IBSSMohammed Shafi Shajakhan1-9/+0
commit 2031b4c2b4904f7448ab9e4bc6b9bf16e32709f5 upstream. this patch is dependent on the patch "cfg80211: fix interface combinations" In ath9k currently we have ADHOC interface as a single incompatible interface. when drv_add_interface is called during resume we got to consider number of vifs already present in addition to checking the drivers 'opmode' information about ADHOC. we incorrectly assume an ADHOC interface is already present. Then we may miss some driver specific data for the ADHOC interface after resume. The above mentioned checks can be removed from the driver, as the patch 'cfg80211: fix interface combinations' ensures that if an interface type is not advertised by the driver in any of the interface combinations(via ieee80211_iface_combination) then it shall be treated as a single incompatible interface. Fixes the following warning on suspend/resume with ibss interface. ath: phy0: Cannot create ADHOC interface when other interfaces already exist.

The commit "ath9k: Fix invalid noisefloor reading due to channel update" preserves the current channel noisefloor readings before updating channel type at the same channel index. It is also updating the curchan pointer. As survey updation is also referring curchan pointer to fetch the appropriate index, which might leads to invalid memory access. This patch partially reverts the change and stores the noise floor history buffer before updating channel type w/o updating curchan.

2011-12-19ath9k_hw: make bluetooth coexistence support optional at compile timeFelix Fietkau1-6/+7
Many systems (e.g. embedded systems) do not have wifi modules connected to bluetooth modules, so bluetooth coexistence is irrelevant there. With the addition of MCI support, ath9k picked up quite a bit of extra code that can be compiled out this way. This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for querying the bluetooth coexistence scheme, allowing the compiler to eliminate code that uses it, with only very little use of #ifdef. On MIPS this reduces the total size for the modules by about 20k. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-12-08ath9k: use config.enable_ani to check if ani should be performedNikolay Martynov1-2/+3
Currently in ath9k code there is an attempt which is meant to disable ANI for ar9100 and ar9340. But it doesn't really achieve this. All it does is disable ANI init and setup (i.e. calls to ath9k_hw_ani_setup and ath9k_hw_ani_init). Since ath9k_hw_ani_setup is not called ah->config.ani_poll_interval is never initialized (i.e. it is always zero) and ath_ani_calibrate always executes ANI procedures (over uninitialized ANI parameters). Moreover, ath_ani_calibrate is being called each 1ms because common->ani.timer is set to zero interval because ah->config.ani_poll_interval==0 (and thus smallest value of all intervals). Normally it should not be called this often. This patch changes the code so config.enable_ani is used to check if ANI should be performed. config.enable_ani is initialized to true by default. This patch sets it to false for ar9100 and ar9340. Signed-off-by: Nikolay Martynov <mar.kolya@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Turning off the radio when mac80211 tells the driver that it's idle is not a good idea, as idle interfaces might still occasionally scan or send packets. The only time the radio can be safely turned off is when drv_stop has been called. In the mean time, use sc->ps_idle only to indicate network sleep vs full sleep.

2011-12-08ath9k: always issue a full hw reset after waking up from full-sleep modeFelix Fietkau1-2/+10
After waking up from full sleep, registers are accessible, but rx/tx typically fails. A fast channel change will not recover from this, so ensure that a full-sleep -> wake transition is always followed by a full reset. The reason why this hasn't created any serious problems yet is that it's hidden by the (wrong) behavior of enabling/disabling the radio when the wiphy idle state changes.

2011-10-03mac80211: pass vif param to conf_tx() callbackEliad Peller1-1/+2
tx params should be configured per interface. add ieee80211_vif param to the conf_tx callback, and change all the drivers that use this callback. The following spatch was used: @rule1@ struct ieee80211_ops ops; identifier conf_tx_op; @@ ops.conf_tx = conf_tx_op; @rule2@ identifier rule1.conf_tx_op; identifier hw, queue, params; @@ conf_tx_op ( - struct ieee80211_hw *hw, + struct ieee80211_hw *hw, struct ieee80211_vif *vif, u16 queue, const struct ieee80211_tx_queue_params *params) {...} Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W.

2011-09-30mac80211: let drivers inform it about per TID buffered framesJohannes Berg1-2/+1
For uAPSD implementation, it is necessary to know on which ACs frames are buffered. mac80211 obviously knows about the frames it has buffered itself, but with aggregation many drivers buffer frames. Thus, mac80211 needs to be informed about this. For now, since we don't have APSD in any form, this will unconditionally set the TIM bit for the station but later with uAPSD only some ACs might cause the TIM bit to be set. ath9k is the only driver using this API and I only modify it in the most basic way, it won't be able to implement uAPSD with this yet. But it can't do that anyway since there's no way to selectively release frames to the peer yet. Since drivers will buffer frames per TID, let them inform mac80211 on a per TID basis, mac80211 will then sort out the AC mapping itself.

After 'ath9k: optimize ath9k_ps_restore', it would only send the device to network sleep and not to full sleep anymore, potentially causing more battery drain.

2011-09-27mac80211: add ieee80211_vif param to tsf functionsEliad Peller1-3/+5
TSF can be kept per vif. Add ieee80211_vif param to set/get/reset_tsf, and move the debugfs entries to the per-vif directory. Update all the drivers that implement these callbacks. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-09-19ath9k: Reset caldata on radio enableRajkumar Manoharan1-0/+1
Not doing so, the caldata continues to retain older history values learned on that channel. It is always safer to start noise floor calibration from the defaults after the assoication. So this patch resets the nf history buffer when none of the STA vifs are associated. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

ath_hw_cycle_counters_update only needs to be called if the power state changes. Most of the time this does not happen, even when ps_usecount goes down to 0. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
