git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== pull request: wireless-next 2014-07-25 Please pull this batch of updates intended for the 3.17 stream! For the mac80211 bits, Johannes says: "We have a lot of TDLS patches, among them a fix that should make hwsim tests happy again. The rest, this time, is mostly small fixes." For the Bluetooth bits, Gustavo says: "Some more patches for 3.17. The most important change here is the move of the 6lowpan code to net/6lowpan. It has been agreed with Davem that this change will go through the bluetooth tree. The rest are mostly clean up and fixes." and, "Here follows some more patches for 3.17. These are mostly fixes to what we've sent to you before for next merge window." For the iwlwifi bits, Emmanuel says: "I have the usual amount of BT Coex stuff. Arik continues to work on TDLS and Ariej contributes a few things for HS2.0. I added a few more things to the firmware debugging infrastructure. Eran fixes a small bug - pretty normal content." And for the Atheros bits, Kalle says: "For ath6kl me and Jessica added support for ar6004 hw3.0, our latest version of ar6004. For ath10k Janusz added a printout so that it's easier to check what ath10k kconfig options are enabled. He also added a debugfs file to configure maximum amsdu and ampdu values. Also we had few fixes as usual." On top of that is the usual large batch of various driver updates -- brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action. Rafał has also been very busy with b43 and related updates. Also, I pulled the wireless tree into this in order to resolve a merge conflict... P.S. The change to fs/compat_ioctl.c reflects a name change in a Bluetooth header file... ==================== Signed-off-by: David S. Miller <[email protected]>

2014-07-14ath6kl: convert ar6004 hardware flags to firmware feature flagsKalle Valo1-9/+7
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.

2013-06-01ath6kl: Check wmi ready event status before validating abi versionRaja Mani1-7/+7
There is no point to check firmware ABI version when the driver fails to wait for WMI_READY event during the boot time.

2013-03-18ath6kl: Fix the byte alignment rule to avoid loss of bytes in a TCP segmentMyoungje Kim1-2/+2
Either first 3 bytes of the first received tcp segment or last one over MTU size file can be loss due to the byte alignment problem. Although ATH6KL_HTC_ALIGN_BYTES was defined for 'extra bytes for htc header alignment' in the patch "Fix buffer alignment for scatter-gather I/O"(1df94a857), there exists the bytes loss issue which means that it will be truncated 3 bytes in the transmitted file contents if a file which has over MTU size is transferred through TCP/IP stack. It doesn't look like TCP/IP stack bug of 3.5 or the latest version of kernel but the byte alignment issue. This patch is to use the roundup() function for the byte alignment rather than the predefined ATH6KL_HTC_ALIGN_BYTES. kvalo: fixed indentation Signed-off-by: Myoungje Kim <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2013-03-18ath6kl: cold reset target after host warm bootKalle Valo1-1/+12
Julien reported that ar6004 usb device fails to initialise after host has been rebooted and power is still on for the ar6004 device. He found out that doing a cold reset fixes the issue. I wasn't sure what would be the best way to detect if target needs a reset so I settled on checking a timeout from htc_wait_recv_ctrl_message().

2013-03-18ath6kl: fix usb related error handling and warningsKalle Valo1-4/+6

Rename ath6kl_cleanup_vif function as 'ath6kl_cfg80211_vif_stop' which is the more appropriate name considering the functionality of the module and vif specific cleanup is actually done by ath6kl_cfg80211_vif_cleanup. Also move it to cfg80211.c. Also make ath6kl_cfg80211_sta_bmiss_enhance as static function. This addresses a FIXME/TODO.

2012-10-24ath6kl: Fix inactivity timeout for AR6004Mohammed Shafi Shajakhan1-5/+8
Currently AR6004 handles the inactivity timeout resolution in minutes rather than seconds. So parse the inactivity timeout to the firmware in minutes. For now we will cleanup the inactive station entries to the nearest converted minutes (ex: an inactive time of 70 seconds would take atleast 2 - 3 minutes) Tested with surprise removal of client cards/host shutdown.

2012-10-24ath6kl: Fix reconnection issue after recoveryVasanthakumar Thiagarajan1-1/+5
Disallowing any wmi commands while re-initializing the firmware results in connection failures after recovery is done in open/WEP mode. To fix this, clear WMI_READY, to make sure no wmi command is tried while fw is down. Remove ATH6KL_STATE_RECOVERY state check in ath6kl_control_tx() so that any configuration during fw init time will go through using wmi commands.

2012-10-24ath6kl: Add support to detect fw error through heart beatVasanthakumar Thiagarajan1-6/+0
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 <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2012-10-24ath6kl: Recover from fw crashVasanthakumar Thiagarajan1-0/+19
Re-initialize the target when fw crash is reported. This would make the device functional again after target crash. During the target re-initialization it is made sure that target is not bugged with data/cmd request, ar->state ATH6KL_STATE_RECOVERY is used for this purpose.

2012-10-24ath6kl: rework scheduled scanThomas Pedersen1-0/+6
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.
