* ath9k_hw: remove confusing logic inversion in an ANI variableFelix Fietkau2012-06-20

* ath9k_hw: fix OFDM weak signal detection handlingFelix Fietkau2012-06-20
| | | | | | | | | | | | | | | | | | | | | Commit "ath9k_hw: improve ANI processing and rx desensitizing parameters" was unifying some code related to overriding OFDM weak signal detection, but seems to have gotten some of the original intent wrong, probably because of a misnamed variable. The beacon RSSI is only valid in station mode, and the main reason to check it in ath9k_hw_set_ofdm_nil is to make sure that OFDM weak signal detection stays enabled if the RSSI is low, even when the OFDM noise immunity entry is supposed to disable it. The above commit removed the mode checks and changed the code so that OFDM weak signal detection would only be changed if the rssi is high, which is wrong for everything but client mode. This patch restores the old behavior in a simplified form. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | I don't know why somebody decided to keep a cached copy of beacon rssi in a variable called 'noiseFloor', but the caching is unnecessary and the variable name is confusing, so let's just get rid of it entirely.

| * iwlwifi: use minimal time for radio reset scanJohannes Berg2012-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | The effect of using a short single-channel scan to reset the radio is that scanning a channel that isn't in use needs to re-tune the radio. This means that the dwell time is irrelevant, so use a shorter time. While at it, clean up the code for this a bit.

| * iwlwifi: delay ROC if doing internal reset scanJohannes Berg2012-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the device is doing an internal radio reset scan, ROC can be rejected to the supplicant with busy status which confuses it. One option would be to queue the ROC and handle it later, but since the radio reset scan is very quick we can just wait for it to finish instead. Also add a warning since we shouldn't run into the case of having a scan active when requesting a ROC in any other case since mac80211 will not scan while ROC or ROC while scanning.

This has been root caused to the delay in releasing pending a-mpdu subframes in reorder buffer. Right now the timeout value is 400ms, there is also a race condition where timeout handler can be delayed to run at an extra timeout interval. This patch reduces the timout interval to reasonable 100ms and makes sure releasing pending frames are not skipped in the timeout handler by removing the flag (rxtid->progress) which can delay the timeout logic.

This will fix the following issue: 1) Disable 11n from supplicant and start a P2P GO. 2) In beacon frames no HT-CAP IE is seen which is expected. 3) Now remove the P2P GO and kill the supplicant. 4) Beacon stops 5) Now using iw associate to an external AP in 5 GHZ 6) In 5 GHZ no HT IE going in assoc request but when associated in 2.4 GHZ can see HT IES over the air in assoc request. In the code for del_beacon in cfg80211.c,set_ht_cap is being called first for 2.4 GHZ and then for 5 GHZ. When called for the first time for 2.4 GHZ the enable flag will be set to true and so when called for the second time for 5 GHZ it just returns after checking the flag. Also using this one can have different HT capabilities per band (for example one may decide not to use 20/40 in 2.4 GHZ but use it in 5 GHZ). So maintaining a single context is not ok. it is true for even the enable/disable flag and other HT capabilities as well Signed-off-by: Kiran Reddy <c_lreddy@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

This check was added by commit b5257c952dda24df7078c74b7b811b44c6e49206 as part of workaround for hardware issue. Commit 2e42e4747ea72943c21551d8a206b51a9893b1e0 that replaced compare_ether_addr with ether_addr_equal relieved that this compare to be inverse of what it should be. Compare was added as response to hardware bug, where bssid-list does not contain BSSID and other information of currently connected AP (spec insists that device must provide this information in the list when connected). Lack bssid-data on current connection then causes WARN_ON somewhere in cfg80211. Workaround was to check if bssid-list returns current bssid and if it does not, manually construct bssid information in other ways. And this workaround worked, with inverse check. Which must mean that when hardware is experiencing the problem, it's actually returning empty bssid-list and this check didn't make any difference for workaround. However inverse check causes workaround be activated when bssid-list returns only entry, currently connected BSSID. That does not cause problems in itself, just slightly more inaccurate information in scan-list. Cc: Joe Perches <joe@perches.com> Cc: David S.

| * | | ath9k: remove incompatible IBSS interface check in change_ifaceMohammed Shafi Shajakhan2012-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | '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. if there are more than one interfaces present and changing them to incompatible interface type is not possible. These checks will be properly handled by cfg80211_change_iface -> cfg80211_can_change_interface. this patch is dependent on 'cfg80211: fix interface combinations' Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.

| * | | ath9k: Fix a WARNING on suspend/resume with IBSSMohammed Shafi Shajakhan2012-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
