* cfg80211: allow passing frame type to cfg80211_inform_bss()Johannes Berg2014-08-26
| | | | | | | | | | | | | When using the cfg80211_inform_bss[_width]() functions drivers cannot currently indicate whether the data was received in a beacon or probe response. Fix that by passing a new enum that indicates such (or unknown). For good measure, use it in ath6kl.

* cfg80211: remove @gfp parameter from cfg80211_rx_mgmt()Vladimir Kondratiev2014-08-26
| | | | | | | | | | | | | | In the cfg80211_rx_mgmt(), parameter @gfp was used for the memory allocation. But, memory get allocated under spin_lock_bh(), this implies atomic context. So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake), and it should be this way or warning triggered in the memory allocation code. Remove @gfp parameter as no actual choice exist, and use hard coded GFP_ATOMIC for memory allocation.

* ath6kl: convert ar6004 hardware flags to firmware feature flagsKalle Valo2014-07-14
| | | | | | | | | | | | | The functionality defined through these flags were actually firmware features which can change between firmware versions. To make it possible to support different firmware versions with the same driver, convert the flags to firmware feature flags. For backwards compatibility support for old ar6004 firmware FW API 3 or smaller images we forcefully set the feature bits in the driver. Starting from FW API 5 the firmware image needs to set them.

| * cfg80211: constify more pointers in the cfg80211 APIJohannes Berg2014-05-19
| | | | | | | | | | | | | | | | | | | | This also propagates through the drivers. The orinoco driver uses the cfg80211 API structs for internal bookkeeping, and so needs a (void *) cast that removes the const - but that's OK because it allocates those pointers.

| * cfg80211: remove remain-on-channel channel typeJohannes Berg2012-11-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As mwifiex (and mac80211 in the software case) are the only drivers actually implementing remain-on-channel with channel type, userspace can't be relying on it. This is the case, as it's used only for P2P operations right now. Rather than adding a flag to tell userspace whether or not it can actually rely on it, simplify all the code by removing the ability to use different channel types. Leave only the validation of the attribute, so that if we extend it again later (with the needed capability flag), it can't break userspace sending invalid data.

* | ath6kl: Add support to detect fw error through heart beatVasanthakumar Thiagarajan2012-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support to detect fw error condition by sending periodic message (heart beat challenge) to firmware. Upon reception of the message, fw would send a response event to driver. When there are no reponses from fw for about 5 cmd driver would trigger the recovery logic assuming that fw has gone into an error state. Capable fw will advertise this capability through ATH6KL_FW_CAPABILITY_HEART_BEAT_POLL bit. This feature is disabled by default, can be enabled through a modparam (heart_beat_poll). This modparam also confiures the polling interval in msecs. Signed-off-by: Vasanthakumar Thiagarajan <vthiagar@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

The access to wmi_rate_tbl array may be out of range if sgi is 1. This may cause the return value of ath6kl_wmi_get_rate() function is incorrect link rate.

* | ath6kl: rework scheduled scanThomas Pedersen2012-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reflects changes in the firmware scheduled scan implementation to behave better in cases with multiple concurrent vifs. Major changes: - scheduled scan filters and state are now programmed per-vif. - decouple scheduled scan from host sleep. To maintain graceful failure with old firmwares, a new firmware capability bit is introduced: ATH6KL_FW_CAPABILITY_SCHED_SCAN_V2. ath6kl simply won't advertise scheduled scan to cfg80211 if the SCHED_SCAN_V2 is not supported. Since firmwares from here on out won't support the previous implicit API for scheduled scan (set WoW filters and host sleep), bump the firmware API to protect old drivers. Unfortunately, due to firmware RAM constraints ath6kl still cannot expect a scan complete event at the end of a scheduled scan results cycle, so the sched_scan_timer is retained.

* | ath6kl: fix incorrect use of IEEE80211_NUM_BANDSKalle Valo2012-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ath6kl was incorrectly assuming that IEEE80211_NUM_BANDS will always be 2 and used that also in the firmware WMI interface definitions. But after the support for 60 GHz was added to cfg80211 IEEE80211_NUM_BANDS changed to 3 and this can cause all sort of problems, possibly even memory corruption. I only found this during code review and didn't notice any bugs, but I'm sure there are a few lurking somewhere. To fix this rename unused A_NUM_BANDS to ATH6KL_NUM_BANDS, which is always defined to be 2, and use that in WMI. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
