2012-04-16mac80211: Take into account TSF adjustment latency in Toffset setpointJavier Cardona1-1/+7
When testing mesh synchronization we observed a global TSF slowdown that was dependent on the number of synchronized mesh stations. This seems to be caused by the TSF adjustment (read/write) latency. Adding a small margin to the Toffset setpoint solved the problem.

Commit 3a25a8c8 (mac80211: add improved HW queue control) introduced a bug when running in AP mode without the IEEE80211_HW_QUEUE_CONTROL flag set. The ieee80211_check_queues() function always returns -EINVAL, preventing AP mode from starting. To fix this, check whether this flag is set before checking if cab_queue is set properly.

2012-04-16cfg80211: enforce lack of interface combinationsJohannes Berg3-16/+4

2012-04-13brcm80211: smac: only provide valid regulatory hintArend van Spriel1-1/+35
The driver provides a regulatory hint to cfg80211 as obtained from the SPROM. Mostly, this will be a two-letter ISO country code. However, it may obtain special country code similar to the world regulatory domain as used in cfg80211. This patch avoids setting these special codes as the hint is lost to cfg80211.

2012-04-13ath9k_hw: Remove BTCOEX initvalsSujith Manoharan3-20/+0
The MAX_TXPWR table for BTCOEX is not needed for AR9462. Programming these values to the HW results in undesirable behavior - for example, large number of delimiter/data underruns are seen in AES-CCMP mode. Also, registers like AR_PCU_MISC_MODE2 return 0xdeadbeef after the BTCOEX_MAX power table is programmed to the HW, and frames being transmitted end up being looped back to the RX engine, an example being beacon frames in IBSS mode. Remove this table for now - this fixes CCMP performance and general IBSS usage. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
