2011-04-12ath5k: fix slot time handlingFelix Fietkau
Set the slot time based on the mac80211 short slot vs long slot setting instead of just forcing long slot for all CCK-enabled channels. This slightly improves 802.11g mode performance in in my tests.

2011-04-12ath5k: fix SIFS time handlingFelix Fietkau
ath5k uses 8 usec as a sifs time, extracted from the initvals, whereas the standard requires a sifs time of 10. The difference originates from the fact that the SIFS register has an offset of 2 usec. Fix the SIFS time definition to use the standard value of 10 usec and subtract 2 usecs when writing the SIFS register. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2011-02-25mac80211: make tx() operation return voidJohannes Berg
The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.

2011-01-28ath5k: Fix short and long retry configurationBruno Randolf
The register definition for retry configuration on AR5212 was wrong, and simply copied over from AR5210. Update the register definitions from the documentation. Let the short and long retries be configured from mac80211 and use the standard values of 7 and 4 by default. Also we need to make sure we don't export more retries than we are configured for to mac80211 (and the rate module) in hw->max_rate_tries. Also clean up the code by removing unused defines and variables and drop the different values for "station retries" - if these need to be different it can be handled tru ah_retry_long/short.

2010-12-22ath5k: Track current TX power separately from max TX powerBruno Randolf
Add a new variable to keep track of the currently configured tx power. Before max_pwr was re-used for keeping the maximum allowed power as well as the current configuration. Doing a min() on it allows you to lower the txpower, but how would you be able to make it higher again? This patch fixes that by adding a new variable ah_cur_pwr which is used instead of txp_max_pwr to keep the current configuration. txp_max_pwr is used to check if we are within the limits. Another problem fixed by this patch is that it avoids setting a zero txpower when things are initialized first and the current power is not yet set.

2010-11-30ath5k: Support synth-only channel change for AR2413/AR5413Nick Kossifidis
* Add synth-only channel change for AR2413/5413. When we call ath5k_reset with a channel ath5k_hw_reset will first try to set channel on PHY while PHY is running instead of doing a normal full reset. To do this phy_init has to change to implement this functionality. * Clean up change_channel flag, what it really did was skip PCU registers when setting initvals. This is done because on reset PCU registers are not affected (except the registers we set in pcu init and -due to hw problems- TSF). Use a new skip_pcu flag that's not misleading instead. In the future we might use that to also skip PCU reset and save us the TSF etc problems (needs testing because standard practice is to reset everything). * Use fast channel change only when setting channel, and set skip_pcu to false only on init. When we reset the card due to DMA or PHY problems skip pcu but never do a fast channel change. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

* Replace set_slot_time with set_ifs_intervals that also sets the various inter-frame space intervals based on current bwmode. * Clean up AR5210 mess from reset_tx_queue, AR5210 only has one data queue and we set IFS intervals for that queue on set_ifs_intervals so there is nothing left to do for 5210 on reset_tx_queue.

Collect all pieces concering the antenna switch table into one function. Previously it was split up between ath5k_hw_reset() and ath5k_hw_commit_eeprom_settings(). Also we need to set the antenna switch table when ath5k_hw_set_antenna_mode() is called manually (by "iw phy0 antenna set", for example). I'm not sure if we need to set the switchtable at the same place in ath5k_hw_reset() as it was before - it is set later thru ath5k_hw_set_antenna_mode() anyways - but i leave it there to avoid problems(?).

2010-04-07ath5k: Adaptive Noise Immunity (ANI) ImplementationBruno Randolf
This is an Adaptive Noise Imunity (ANI) implementation for ath5k. I have looked at both ath9k and HAL sources (they are nearly the same), and even though i have implemented some things differently, the basic algorithm is practically the same, for now. I hope that this can serve as a clean start to improve the algorithm later. This also adds a possibility to manually control ANI settings, right now only thru a debugfs file: * set lowest sensitivity (=highest noise immunity): echo sens-low > /sys/kernel/debug/ath5k/phy0/ani * set highest sensitivity (=lowest noise immunity): echo sens-high > /sys/kernel/debug/ath5k/phy0/ani * automatically control immunity (default): echo ani-on > /sys/kernel/debug/ath5k/phy0/ani * to see the parameters in use and watch them change: cat /sys/kernel/debug/ath5k/phy0/ani Manually setting sensitivity will turn the automatic control off. You can also control each of the five immunity parameters (noise immunity, spur immunity, firstep, ofdm weak signal detection, cck weak signal detection) manually thru the debugfs file. This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
