2011-01-28ath9k: fix tx queue index confusion in debugfs codeFelix Fietkau3-20/+21
Various places printing tx queue information used various different ways to get a tx queue index for printing statistics. Most of these ways were wrong. ATH_TXQ_AC_* cannot be used as an index for sc->tx.txq, because it is only used internally for queue assignment. One place used WME_AC_* as a queue index for sc->debug.stats.txstats, however this array uses the ath9k_hw queue number as well. Fix all of this by always using the ath9k_hw queue number as an index, and always looking it up by going through sc->tx.txq_map.

2011-01-28ath9k: remove the virtual wiphy debugfs interfaceFelix Fietkau1-133/+4
It does not make much sense to keep the current virtual wiphy implementation any longer - it adds significant complexity, has very few users and is still very experimental. At some point in time, it will be replaced by a proper implementation in mac80211. By making the code easier to read and maintain, removing virtual wiphy support helps with fixing the remaining driver issues and adding further improvements.

2011-01-28ath9k: clean up the code that wakes the mac80211 queuesFelix Fietkau2-23/+18
Instead of spreading ath_wake_mac80211_queue() calls over multiple places in the tx path that process the tx queue for completion, call it only where the pending frames counter gets decremented, eliminating some redundant checks. To prevent queue draining from waking the queues prematurely (e.g. during a hardware reset), reset the queue stop state when draining all queues, as the caller in main.c will run ieee80211_wake_queues(hw) anyway.

2011-01-27ath9k: fix misplaced debug codeFelix Fietkau2-8/+3
The commit 'ath9k: Add more information to debugfs xmit file.' added more debug counters to ath9k and also added some lines of code to ath9k_hw. Since ath9k_hw is also used by ath9k_htc, its code must not depend on ath9k data structures. In this case it was not fatal, but it's still wrong, so the code needs to be moved back to ath9k.

We need to read and backup AR_WA register value permanently and reading this after the chip is awakened results in this register being zeroed out.

2011-01-25ath9k_hw: Fix incorrect macversion and macrev checksSenthil Balasubramanian1-2/+2
There are few places where we are checking for macversion and revsions before RTC is powered ON. However we are reading the macversion and revisions only after RTC is powered ON and so both macversion and revisions are actully zero and this leads to incorrect srev checks Incorrect srev checks can cause registers to be configured wrongly and can cause unexpected behavior. Fixing this seems to address the ASPM issue that we have observed. The laptop becomes very slow and hangs mostly with ASPM L1 enabled without this fix. fix this by reading the macversion and revisisons even before we start using them. There is no reason why should we delay reading this info until RTC is powered on as this is just a register information.

2011-01-24wl12xx: Increase scan channel dwell time for passive scansJuuso Oikarinen2-11/+11
The passive scan channel dwell time currently used is 30-60TU. A typical beacon interval for AP's is 100TU. This leads to a ~30% worst-case probability of finding an AP via passive scanning. For 5GHz bands for DFS frequencies passive scanning is the only scanning option. Hence for these, the probability of finding an AP is very low. To fix this, increase the passive channel scan dwell times (also the early leave value, as 5GHz channels are still typically very silent.) Use a value of 100TU, because that covers most typical AP configurations. Based on testing the probability of finding an AP (100TU beacon interval) on a single scan round are as follows (based on 100 iterations): dwell min/max (TU) | probability ---------------------+------------ 30/60 | 35% 60/60 | 56% 80/80 | 77% 100/100 | 100% Total scan times now and after the change: Region | Before (s) | After (s) -------+------------+---------- 00 | 0.77 | 1.48 FI | 0.95 | 2.01 US | 0.91 | 1.76 Signed-off-by: Juuso Oikarinen <juuso.oikarinen@nokia.com> Reviewed-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
