2009-11-10ath5k: don't reset mcast filter when configuring the modeBob Copeland
We should not zero out the multicast hash when configuring the operating mode, since a zero value means all multicast frames will get dropped. Also, ath5k_mode_setup() gets called after any reset, so the hash already set up in configure_filter() is lost. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W.

2009-10-30ath9k: fix misplaced semicolon on rate controlLuis R. Rodriguez
The patch e43419f9: ath9k: downgrade assert in rc.c for invalid rate downgraded an ASSERT to a WARN_ON() but also misplaced a semicolon at the end of the second check. What this did was force the rate control code to always return the rate even if we should have warned about it. Since this should not have happened anymore anyway this fix isn't critical as the proper rate would have been returned anyway.

2009-09-29ar9170: fix bug in iq-auto calibration value calculationChristian Lamparter
This patch fixes a embarrassing bug which was introduced by: "[PATCH] ar9170: implement frequency calibration for one-stage/openfw" The phy_data variable initialization has to done outside the for-loop scope. This is because the for-loop uses u32 phy_data variable more like a 4-byte field. But in each run only a single byte is calculated. Therefore phy_data content needs to stay the same for at least 3 more iterations, before the complete set can be uploaded.

2009-09-23ath9k: Fix RFKILL bugsSujith
This patch fixes 2 issues in RFKILL: * Calling wiphy_rfkill_stop_polling() in ath9k_stop would mean that the driver cannot report HW status when the radio is re-enabled. Move this to ath_detach(). * Calling ath_radio_{enable/disable} without checking the current state results in ath_radio_enable() being called repeatedly for every invocation of rfkill_poll(). This is not needed in any case since wiphy_rfkill_set_hw_state() would call ->stop() if the radio has been disabled.

2009-09-08ath,ar9170: implemented conformance test limit calc. for tx powerJoerg Albert
apply the conformance test limits (CTL) stored in the eeprom upon the values calculated for the tx power (ar->power_*). This is based on the implementation in the vendor driver (hal/hpmain.c, line 3700 ff.) with one difference: If any ctl mode isn't found in the eeprom, we fall back to the "lower", legacy modes (5GHT20,11A or 2GHT20,11G,11B). Otus only did 5GHT20->11A. Currently CTL are applied for the FCC group only. Signed-off-by: Joerg Albert <jal2@gmx.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-09-08ath9k: Fix channelFlags for 2GHZSujith
CHANNEL_G has to be set for 2GHZ channels since IS_CHAN_G() checks for this in channelFlags and not in chanmode. To make things messier, ath9k_hw_process_ini() checks for CHANNEL_G in chanmode and not in channelFlags. The supreme, brain-searing fix is to set the flag in both cases.

The `val' variable in ath5k_eeprom_read_turbo_modes() is used uninitialized. gcc 4.4.1 with -fno-inline-functions-called-once reports it: eeprom.c: In function 'ath5k_eeprom_read_turbo_modes': eeprom.c:441: warning: 'val' may be used uninitialized in this function Comparing the code to the Atheros HAL, it's clear that the split between ath5k_eeprom_read_modes() and ath5k_eeprom_read_turbo_modes() was incorrect. The Atheros HAL reads both turbo and non-turbo data from EEPROM in one function. Some turbo mode parameters are derived from the same EEPROM values as non-turbo parameters, just from different bits. Merge ath5k_eeprom_read_turbo_modes() into ath5k_eeprom_read_modes() to fix the warning. The actual values and offsets have been cross-checked against Atheros HAL.
