2014-09-27ath9k: Fix queue managementSujith Manoharan1-7/+3
Since we use IEEE80211_HW_QUEUE_CONTROL now, the CAB/Offchannel queues are registered as the last two queues. There is no need to check and reassign the queues in the TX start()/done() routines. CAB frames will not reach the tx() callback since we set IEEE80211_HW_HOST_BROADCAST_PS_BUFFERING and pull the buffered frames during beacon transmission. We also don't have a special HW queue for handling off-channel frames. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-09-27rtl818x_pci: add RSSI information for rtl8187SEandrea.merello1-5/+23
This patch makes the driver to report signal strength information to mac80211 for rtl8187se boards. It differs from my previous RFT patch: http://marc.info/?l=linux-wireless&m=140155388332534&w=2 because: - I have now a working rtl8187se card, so I could serve my RFT by myself. :) - CCK measurement code has changed a bit, but it does basically the same things. - OFDM measurement method is changed because the older method reported incorrect measures, at least for signals stronger than -40dBm). CCK measurement seems quite good. OFDM seems less accurate, but this is the same as the "reference" staging driver dose. I wanted not to change things just to make measures of _one_ (my) card a bit more close to what _I_ (in my setup) expected.. IMHO results are still good enough to justify reporting signal in dBm rather than in "unspecified" units, so this is what this patch actually does. Results of my tests with a working rtl8187se card connected with coaxes and various RF attenuators to my AP are: Input (approx) | CCK meas | OFDM meas -------------------------------------- -30dBm | -32dBm | -31dBm -40dBm | -40dBm | -41dBm -50dBm | -50dBm | -55dBm -60dBm | -59dBm | -63dBm -70dBm | -69dBm | -73dBm -80dBm | -79dBm | -83dBm Also some real-field tests has been done (no coax, packets in the air) for the CCK measure method, and they resulted in reasonable values.

2014-09-27ath9k: Fix p2p address managementSujith Manoharan2-0/+37
When multiple channel contexts are enabled, a p2p interface that is assigned to a context will have an address that is different from the device mac address, which is used by wpa_s as the p2p device ID. Certain frames like provision requests use the device address and these get dropped since ath9k_calculate_summary_state() iterates over only the active interfaces in a context and the device address is not used. Fix this by adding the device mac address to the bssid mask. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-09-27ath9k: Cache BSS informationSujith Manoharan3-7/+17
Using the BSS information stored in mac80211 directly is racy in certain conditions. For example, in a MCC setup, if the scheduler is switching channels when a local deauth is issued, calculation of the opmode/bssid etc. is incorrect. To avoid this, store the bss params in the driver and use it. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== pull request: wireless-next 2014-09-22 Please pull this batch of updates intended for the 3.18 stream... For the mac80211 bits, Johannes says: "This time, I have some rate minstrel improvements, support for a very small feature from CCX that Steinar reverse-engineered, dynamic ACK timeout support, a number of changes for TDLS, early support for radio resource measurement and many fixes. Also, I'm changing a number of places to clear key memory when it's freed and Intel claims copyright for code they developed." For the bluetooth bits, Johan says: "Here are some more patches intended for 3.18. Most of them are cleanups or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed channels which should now work better together with the L2CAP information request procedure." For the iwlwifi bits, Emmanuel says: "I fix here dvm which was broken by my last pull request. Arik continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal keeps digging into rate scaling code, more to come soon. Besides this, nothing really special here." Beyond that, there are the usual big batches of updates to ath9k, b43, mwifiex, and wil6210 as well as a handful of other bits here and there. Also, rtlwifi gets some btcoexist attention from Larry. Please let me know if there are problems! ==================== Had to adjust the wil6210 code to comply with Joe Perches's recent change in net-next to make the netdev_*() routines return void instead of 'int'.

2014-09-26ath5k: Remove AHB bus supportPaul Bolle6-294/+3
AHB bus support was added in v2.6.38, through commit a0b907ee2a71 ("ath5k: Add AHB bus support."). That code can only be build if the Kconfig symbol ATHEROS_AR231X is set. But that symbol has never been added to the tree. So AHB bus support has always been dead code. Let's remove all code that depends on ATHEROS_AR231X. If that symbol ever gets added to the tree the AHB bus support can be re-added too. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Instead consider the sta state as aggregated as long as there's at least one TID aggregated. This limitation is because the rates table is kept per station and not per TID.

2014-09-21iwlwifi: mvm: report all BA notifs to RSEyal Shapira1-11/+40
Currently BA notifications which don't reclaim any frames would not cause the RS to be called as no skbs are passed to mac80211. This is not optimal as RS can benefit from the statistics of sent vs. acked of such a BA. This can improve the reaction time of the RS algorithm. Also, an upcoming change in the firmware would cause BA timeout to be reported as a BA notif with 0 acked so this change is required for that as well.

2014-09-16iwlwifi: mvm: prepare for scheduler config commandAvri Altman8-19/+165
The scheduler is a HW sub-block that directs the work of the Flow Handler by issuing requests for frame transfers, specifying source and destination. Its primary function is to allocate flows into the TX FIFOs based upon a pre-determined mapping. The driver has some responsibilities to the scheduler, namely initialising and maintaining the hardware registers. This is currently done by directly accessing them, which can cause races with the firmware also accessing the registers. To address this problem, change the driver to no longer directly access the registers but go through the firmware for this if the firmware has support for DQA and thus the new command.
