2011-02-24ath9k_htc: Remove OP_ASSOCIATED variableSujith Manoharan4-41/+74
mac80211 stores the association state in ieee80211_bss_conf. Use this and remove the local state, which is incorrect anyway since it is stored globally and not on a per-VIF basis. Restarting ANI and reconfiguration of HW beacon timers when a scan run ends requires more work. This is handled by iterating over the active interfaces. Finally, remove the useless check for associated status in RX processing. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-02-19ath5k: Correct channel setting for AR2317 chipNikolay Ledovskikh1-0/+1
Correct channel setting function must be used for AR2317. When I tested ahb patch on bullet2 all seemed to work fine, but it couldn't connect another host (using ibss for example). During an analysis I observed that it's transmitting on another channel. I looked into madwifi code and understood that the problem is in channel setting function. So atheros RF2317 not fully handled in the current ath5k version and must be patched.

2011-02-05ath9k: add additional checks for the baseband hang detectionFelix Fietkau2-9/+38
Since even with the latest changes the false positive issue of the baseband hang check is not fully solved yet, additional checks are needed. If the baseband hang occurs, the rx_clear signal will be stuck to high, so we can use the cycle counters to confirm it. With this patch, a hardware reset is only triggered if the baseband hang check returned true three times in a row, with a beacon interval between each check and if the busy time was also 99% or more during the check intervals.

2011-02-05ath: Fix clearing of secondary key cache entry for TKIPJouni Malinen1-1/+4
All register writes to the key cache have to be done in pairs. However, the clearing of a separate MIC entry with hardware revisions that use combined MIC key layout did not do that with one of the registers. Add the matching register write to the following register to make the KEY4 register write actually complete. This is mostly a fix for a theoretical issue since the incorrect entry that could potentially be left behind in the key cache would not match with received frames. Anyway, better make this code clean the entry correctly using paired register writes. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

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.
