This reverts commit 1db5950f. The goal of "iwlwifi: Monitor and recover the aggregation TX flow failure" is to first detect when data transmission stalls and then to recover from this situation with a reset of the radio or the firmware, depending on how bad the transmission failures are. Unfortunately we have found that this change causes excessive resets with its current detection algorithm. It also performs its recovery action when none is really needed, like when we are not associated. Revert this change until the issues have been addressed.

In AP mode, ath_beacon_config_ap only restarts the timer if a TSF restart is requested. Apparently this was added, because this function unconditionally sets the flag for TSF reset. The problem with this is, that ath9k_hw_reset() clobbers the timer registers (specified in the initvals), thus effectively disabling the SWBA interrupt whenever a card reset without TSF reset is issued (happens in a few places in the code). This patch fixes ath_beacon_config_ap to only issue the TSF reset flag when necessary, but reinitialize the timer unconditionally. Tests show, that this is enough to keep the SWBA interrupt going after a call to ath_reset() Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: John W.

Until now it was only possible to have one synchronous command running at any time. If a synchronous command is in progress when a second request arrives then the second command will fail. Create a new mutex specific for this purpose to only allow one synchronous command at a time, but enable other commands to wait instead of fail if a synchronous command is in progress.

When selecting the tx fallback rate, rc.c used a separate variable 'nrix' for storing the next rate index, however it did not use that as reference for further rate index lowering. Because of that, it ended up reusing the same rate for multiple multi-rate retry stages, thus decreasing delivery probability under changing link conditions. This patch removes the separate (unnecessary) variable and fixes fallback the way it was intended to work. This should result in increased throughput and better link stability.

Currently the PSM entry function assumes successful operation, and enables ELP, BET and beacon filtering right away. This is bad, because the PSM entry may fail due to environmental issues, which will cause the ELP, BET and beacon filtering to be illegally enabled (because FW remains in active state.) Fix this by enabling ELP, BET and beacon filtering only after successful entry, and by ensuring the firmware is in active mode after the failure.

The most needed command from nl80211, which Wireless Extensions had, is support for power save mode. Add a simple command to make it possible to enable and disable power save via nl80211. I was also planning about extending the interface, for example adding the timeout value, but after thinking more about this I decided not to do it. Basically there were three reasons: Firstly, the parameters for power save are very much hardware dependent. Trying to find a unified interface which would work with all hardware, and still make sense to users, will be very difficult. Secondly, IEEE 802.11 power save implementation in Linux is still in state of flux. We have a long way to still to go and there is no way to predict what kind of implementation we will have after few years. And because we need to support nl80211 interface a long time, practically forever, adding now parameters to nl80211 might create maintenance problems later on. Third issue are the users. Power save parameters are mostly used for debugging, so debugfs is better, more flexible, interface for this. For example, wpa_supplicant currently doesn't configure anything related to power save mode. It's better to strive that kernel can automatically optimise the power save parameters, like with help of pm qos network and other traffic parameters. Later on, when we have better understanding of power save, we can extend this command with more features, if there's a need for that.
