2010-02-10ath5k: use correct packet type when transmittingBob Copeland
The hardware needs to know what type of frames are being sent in order to fill in various fields, for example the timestamp in probe responses (before this patch, it was always 0).

2010-01-25ath9k: improve max rate retry handlingFelix Fietkau
ath9k currently forces hw->max_rate_tries to 4 to work around rate control inefficiencies. This has some negative side effects, such as rate_control_send_low also using a maximum of 4 tries, which could negatively affect reliability of unicast management frames. This patch pushes the retry limit to the rate control instead, and allows it to use more tries on the last stage to prevent unnecessary packet loss.

2010-01-22ath5k: fix setup for CAB queueBob Copeland
The beacon sent gating doesn't seem to work with any combination of flags. Thus, buffered frames tend to stay buffered forever, using up tx descriptors.

2010-01-19ath9k: fix RTS/CTS handlingFelix Fietkau
The Tx DMA descriptor has two kinds of flags that select RTS/CTS usage. The first one (global for the frame) selects whether RTS/CTS or CTS-to-self should be used, the second one enables RTS/CTS or CTS-to-self usage for an individual multi-rate-retry entry. Previously the code preparing the descriptor only enabled the global flag, if the first MRR series selected the local one. Fix this by enabling the global flag if any of the MRR entries need it. With this patch, rate control can properly select the use of RTS/CTS for all MRR entries except the first one, which is the default behavior.

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.

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.
