* ath5k: Disable fast channel switching by defaultNick Kossifidis2011-06-031-1/+10
| | | | | | | | | | | Disable fast channel change by default on AR2413/AR5413 due to some bug reports (it still works for me but it's better to be safe). Add a module parameter "fastchanswitch" in case anyone wants to enable it and play with it.

| * ath5k: fix tx status reporting issuesFelix Fietkau2011-04-121-10/+6Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During normal operation, minstrel was showing suspicious EWMA probabilities exceeding 100%. It looks like the tx status reporting in ath5k was not properly clearing the rate index for rates which were never attempted. This is caused by uninitialized stale data in the on-stack tx status information, which is reused when more frames are received. To fix this, rely on ts->ts_final_idx to select the last attempted rate, instead of checking whether ts->ts_rate is set. Additionally, the conversion from the driver rate index back to the mac80211 rate index can be dropped, as the mac80211 tx status will still have the original rate index which was used to set up the descriptor. Additionally, one more inaccuracy was fixed - the final rate attempt count only needs to be increased by one if the transmission attempt was successful.

* mac80211: make tx() operation return voidJohannes Berg2011-02-251-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ath5k: use tracing for packet tx/rx dumpBob Copeland2011-01-281-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a few tracepoints to ath5k driver transmit and receive callbacks in order to record packet traffic. We record the entire packet in the trace buffer so that the data can be extracted with trace-cmd and external plugins. Compared to the previous debugging calls, this approach removes an out-of-line function call from the tx and rx paths in the compiled-in-but-disabled case, while improving the ability to process the logged data. A new option, CONFIG_ATH5K_TRACER, is added so that one may disable the tracepoints completely.

* | ath5k: Support synth-only channel change for AR2413/AR5413Nick Kossifidis2010-11-301-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
