* ath5k: fix error handling in ath5k_beacon_sendBob Copeland2011-08-09
| | | | | | | | | | | | | | | This cleans up error handling for the beacon in case of dma mapping failure. We need to free the skb when dma mapping fails instead of nulling and leaking the pointer, and we should bail out to avoid giving the hardware the bad descriptor. Finally, we need to perform the null check after trying to update the beacon, or else beacons will never be sent after a single mapping failure.

| * ath5k: merge ath5k_hw and ath5k_softcPavel Roskin2011-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both ath5k_hw and ath5k_softc represent one instance of the hardware. This duplication is historical and is not needed anymore. Keep the name "ath5k_hw" for the merged structure and "ah" for the variable pointing to it. "ath5k_hw" is shorter than "ath5k_softc", more descriptive and more widely used. Put the combined structure to ath5k.h where the old ath5k_softc used to be. Move some code from base.h to ath5k.h as needed. Remove memory allocation for struct ath5k_hw and the corresponding error handling. Merge iobase and ah_iobase fields.

* | net: remove mm.h inclusion from netdevice.hAlexey Dobriyan2011-06-21
|/ | | | | | | | | | | | | | | | | Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * ath5k: fix tx status reporting issuesFelix Fietkau2011-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Berg2011-02-25
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Fix surveyBruno Randolf2010-12-16
| | | | | | | | | | | | | | The old survey implementation was broken and returned nonsense data. Clear cycle counters and survey data on reset. Since the cycle counters easily overflow it's better to keep a local version of collected survey data (in ms resolution, instead of clockrate) and update this every time survey is retrieved. If survey is retrieved often enough to avoid cycle counter overflows this works fine, otherwise we could update survey more often, like ath9k does. Still only the survey for the current channel is kept. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
