2009-01-29ath9k: Read and write the TSF via debugfsAlina Friedrichsen
This patch adds an ath9k specific entry to read, write and reset the TSF into the debugfs, like in ath5k. This makes debugging the IBSS handling of wifi drivers _much_ easier. Signed-off-by: Alina Friedrichsen <x-alina@gmx.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-01-29ath9k: simplify regulatory codeLuis R. Rodriguez
Now that cfg80211 has its own regulatory infrastructure we can condense ath9k's regulatory code considerably. We only keep data we need to provide our own regulatory_hint(), reg_notifier() and information necessary for calibration. Atheros hardware supports 12 world regulatory domains, since these are custom we apply them through the the new wiphy_apply_custom_regulatory(). Although we have 12 we can consolidate these into 5 structures based on frequency and apply a different set of flags that differentiate them on a case by case basis through the reg_notifier(). If CRDA is not found our own custom world regulatory domain is applied, this is identical to cfg80211's except we enable passive scan on most frequencies. Signed-off-by: Luis R.

2009-01-29ath9k: Handle holding descriptor in TX completion properlySujith
If the current holding descriptor is the last one in the TX queue, *and* it has been marked as STALE, then move it to the free list and bail out, as it has already been processed. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

In 'ath9k_ani_reset' the 'ahp->ah_curani' will be initialized only if 'DO_ANI(ah)' true. In 'ath9k_hw_ani_monitor' we are using 'ahp->ah_curani' unconditionally, and it will cause a NULL pointer dereference on AR9100.

Writing the register at offset 0x98c4 causes a deadlock on the AR913x SoCs.

2009-01-29ath9k: remove superfluous check on changing channelLuis R. Rodriguez
When we try to change the channel in ath9k its because either the configuration indicates we *have* changed channels or HT configuration has changed. In both cases we want to do a reset. Either way mac80211 will inform us when we want to actually change the channel so trust those calls. Although in the patch it may seem as I am doing more code changes I am not, all I am doing is removing the initial branch conditional and shifting the code to the left. Signed-off-by: Luis R.

2009-01-29ath9k: remove ath9k_hw_chan2wmode()Luis R. Rodriguez
The only left users are for timing for ACK timeout, slotime and CTS timeout. We currently use an array CLOCK_RATE to keep these values per mode and since as only will use A and G we can depend on the band to get the appropriate values. We note that we should be using a different clock rate value for CCK, we can do this in separate patch, currently this is being disregarded and should only affect when we want to change the default ACK/CTS timeout or slot time and stuck with using using 802.11b.

2009-01-29ath9k: remove mode specific default noise floor valuesLuis R. Rodriguez
The NOISE_FLOOR array we have is mode specific, and the only possible indexed values are A, B and G. The mode routine only can return G or A, so this is band specific. Then since the values for A and G (5ghz or 2ghz) are the same (-96) we simply remove the array and use a static value. If we later determine we want to use special values for HT configurations we can use the new mac80211 conf_is_ht*() helpers. Signed-off-by: Luis R.
