* ath9k: Enable U-APSD AP mode supportJouni Malinen2014-02-24
| | | | | | | | | mac80211 handles the actual operations, so ath9k can just indicate support for this. Based on initial tests, this combination seems to work fine. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * ath9k: Do not support PowerSave by defaultSujith Manoharan2014-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | Even though we make sure PowerSave is not enabled by default by disabling the flag, WIPHY_FLAG_PS_ON_BY_DEFAULT on init, PS could be enabled by userspace based on various factors like battery usage etc. Since PS in ath9k is just broken and has been untested for years, remove support for it, but allow a user to explicitly enable it using a module parameter.

* | ath9k: Remove ath9k rate controlSujith Manoharan2014-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no benefit in retaining the legacy rate control module in the driver codebase. It is known to be buggy and has less than optimal performance in real-world environments compared with minstrel. The only reason that it was kept when we made the switch to minstrel as default was that it showed higher throughput numbers in a clean/ideal environment. This is no longer the case and minstrel can push ath9k to the same throughput levels. In TCP, with 3-stream cards, more than 295 Mbps can be obtained in open air, with 2-stream cards, 210 Mbps is easily reached. To test performance issues, instead of using a broken rate control module, it is better to use the fixed-rate interface provided by mac80211 anyway. The ath9k RC has not received any bug fixes in years and is just bit-rotting away - this patch removes it. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

* | ath9k: Remove RX PollSujith Manoharan2014-01-03
| | | | | | | | | | | | | | | | | | | | | | | | This patch removes the convoluted and hacky method of monitoring for connectivity. We rely on mac80211's connection loss logic and doing it in the driver is not necessary. The HW check for MAC/BB hangs is also simplified, there is no need to have a separate work instance for it.

* ath9k: Use a separate TX gain table for WZR-HP-G450HSujith Manoharan2013-12-09
| | | | | | | | | | | | | | | | | | | | The Buffalo device WZR-HP-G450H uses the index 3 for TX gain, which is set to the high_power table currently. Later variants of the router use the same index, but instead refer to the low_ob_db gain table. This is not handled in the driver since there is no way to distinguish board revisions and the high_power table is used (incorrectly) for the newer variants. By default, devices based on AR9300 using the TX gain index 3 have to use the high_power table. To make sure that WZR-HP-G450H is not broken when the high_power table is updated, use a separate array based on information obtained from the platform data. The current situation where only the original variant of WZR-HP-G450H works properly stays unchanged. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

* ath9k: use a timer to put hardware into full sleepFelix Fietkau2013-12-02
| | | | | | | | | | | | When operating in client mode, the short period of time between scanning and associating is often enough to put the hardware through several FULL-SLEEP <-> AWAKE transitions, each wakeup requiring a reset to fully recover the hardware.

* ath9k: Use correct PCIE initvals for AR9485Sujith Manoharan2013-11-11
| | | | | | | | | | | | | | | | | Currently, the PLL is turned off for AR9485 when switching to a low power state, but AR9485 has an issue where the card will become unresponsive if left idle for a long time without any traffic. To fix this, force the PLL to always be on using a different initval array, ar9485_1_1_pll_on_cdr_on_clkreq_disable_L1. This is done for most of the AR9485 based cards like HB125, WB225 etc. but certain models require the feature to be turned off. Identify such cards and use default values for them.

* ath9k: add TX99 supportLuis R. Rodriguez2013-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TX99 support enables Specific Absorption Rate (SAR) testing. SAR is the unit of measurement for the amount of radio frequency(RF) absorbed by the body when using a wireless device. The RF exposure limits used are expressed in the terms of SAR, which is a measure of the electric and magnetic field strength and power density for transmitters operating at frequencies from 300 kHz to 100 GHz. Regulatory bodies around the world require that wireless device be evaluated to meet the RF exposure limits set forth in the governmental SAR regulations.
