2010-01-25ath9k: fix eeprom INI values override for 2GHz-only cardsFelix Fietkau
Among other changes, this commit: commit 06d0f0663e11cab4ec5f2c143a118d71a12fbbe9 Author: Sujith <Sujith.Manoharan@atheros.com> Date: Thu Feb 12 10:06:45 2009 +0530 ath9k: Enable Fractional N mode changed the hw attach code to fix up initialization values only for dual band devices, however the commit message did not give a reason as to why this would be useful or necessary. According to tests by Jorge Boncompte, this breaks at least some 2GHz-only cards, so the code should be changed back to the unconditional INI fixup.

2010-01-19ath9k: fix beacon slot/buffer leakFelix Fietkau
When cleaning up beacon buffers and slots, ath9k currently checks if sc->ah->opmode is set to a beacon related mode before cleaning up buffers. An unfortunate ordering of interface up/down commands can lead to sc->ah->opmode being set to monitor mode, while there are AP interfaces present on the same wiphy. Always cleaning up beacon buffers if present fixes this issue. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-01-15ath9k: cleanup slot time and ack/cts timeout handlingFelix Fietkau
Previously ath9k left the initialization of slot timing and ACK/CTS timeout to the mode specific initvals. This does not handle short vs long slot in 2.4 GHz and uses a rather strange value for the 2.4 GHz ACK timeout (64 usec). This patch uses the proper ath9k_hw functions for setting slot time and timeouts and also implements the switch between short and long slot time in 2.4 GHz Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2010-01-12ath5k: Implement mac80211 callback set_coverage_classLukáš Turek
The callback sets slot time as specified in IEEE 802.11-2007 section 17.3.8.6 (for 20MHz channels only for now) and raises ACK and CTS timeouts accordingly.

2010-01-12ath5k: Reimplement clock rate to usec conversionLukáš Turek
The original code was correct in 802.11a mode only, 802.11b/g uses different clock rates. The new code uses values taken from FreeBSD HAL and should be correct for all modes including turbo modes. The former rate calculation was used by slope coefficient calculation function ath5k_hw_write_ofdm_timings. However, this function requires the 802.11a values even in 802.11g mode. Thus the use of ath5k_hw_htoclock was replaced by hardcoded values. Possibly the slope coefficient calculation is not related to clock rate at all.

The conversion was moved outside the hardware-specific branches. The original code also limited minimum slot time to 9, while turbo modes use 6, this was fixed too.

2010-01-12ath9k: re-enable ps by default for new single chip familiesLuis R. Rodriguez
The newer single chip hardware family of chipsets have not been experiencing issues with power saving set by default with recent fixes merged (even into stable). The remaining issues are only reported with AR5416 and since enabling PS by default can increase power savings considerably best to take advantage of that feature as this has been tested properly. For more details on this issue see the bug report: http://bugzilla.kernel.org/show_bug.cgi?id=14267 We leave AR5416 with PS disabled by default, that seems to require some more work.

2010-01-04ath5k: Fix eeprom checksum check for custom sized eepromsLuis R. Rodriguez
Commit 8bf3d79bc401ca417ccf9fc076d3295d1a71dbf5 enabled EEPROM checksum checks to avoid bogus bug reports but failed to address updating the code to consider devices with custom EEPROM sizes. Devices with custom sized EEPROMs have the upper limit size stuffed in the EEPROM. Use this as the upper limit instead of the static default size. In case of a checksum error also provide back the max size and whether or not this was the default size or a custom one. If the EEPROM is busted we add a failsafe check to ensure we don't loop forever or try to read bogus areas of hardware.

2009-12-28ath5k: fix SWI calibration interrupt stormBob Copeland
The calibration period is now invoked by triggering a software interrupt from within the ISR by ath5k_hw_calibration_poll() instead of via a timer. However, the calibration interval isn't initialized before interrupts are enabled, so we can have a situation where an interrupt occurs before the interval is assigned, so the interval is actually negative. As a result, the ISR will arm a software interrupt to schedule the tasklet, and then rearm it when the SWI is processed, and so on, leading to a softlockup at modprobe time. Move the initialization order around so the calibration interval is set before interrupts are active. Another possible fix is to schedule the tasklet directly from the poll routine, but I think there are additional plans for the SWI.
