2008-10-14ath9k/mac80211: disallow fragmentation in ath9k, report to userspaceJohannes Berg
As I've reported, ath9k currently fails utterly when fragmentation is enabled. This makes ath9k "support" hardware fragmentation by not supporting fragmentation at all to avoid the double-free issue. The patch also changes mac80211 to report errors from the driver operation to userspace. That hack in ath9k should be removed once the rate control algorithm it has is fixed, and we can at that time consider removing the hw fragmentation support entirely since it's not used by any driver.

2008-10-06ath9k: enable ANI to help with noisy environmentsLuis R. Rodriguez
This enables Adaptive Noise Immunity (ANI) on ath9k. ANI is as algorithm designed to minimize the detrimental effects of time-varying interferences. This should help with throughput in noisy environments. To use ANI we re-enable the MIB interrupt. Since ANI works on a timer and updates the noise floor we take advantage of this and also report a non-static noise floor now to mac80211.

2008-09-24mac80211: clean up rate control APIJohannes Berg
Long awaited, hard work. This patch totally cleans up the rate control API to remove the requirement to include internal headers outside of net/mac80211/. There's one internal use in the PID algorithm left for mesh networking, we'll have to figure out a way to clean that one up and decide how to do the peer link evaluation, possibly independent of the rate control algorithm or via new API. Additionally, ath9k is left using the cross-inclusion hack for now, we will add new API where necessary to make this work properly, but right now I'm not expert enough to do it. It's still off better than before. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-09-02ath9: Fix ath_rx_flush_tid() for IRQs disabled kernel warning message.Senthil Balasubramanian
This patch addresses an issue with the locking order. ath_rx_flush_tid() uses spin_lock/unlock_bh when IRQs are disabled in sta_notify by mac80211. As node clean up is still pending with ath9k and this problematic portion of the code is expected to change anyway, thinking of a proper fix may not be worthwhile. So having this interim fix helps the users to get rid of the kernel warning message.
