2014-04-09ath9k_hw: reduce ANI firstep range for older chipsFelix Fietkau
Use 0-8 instead of 0-16, which is closer to the old implementation. Also drop the overwrite of the firstep_low parameter to improve stability. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-04-09ath9k: Enable DFS only when ATH9K_DFS_CERTIFIEDJanusz Dziedzic
Add DFS interface combination only when CONFIG_ATH9K_DFS_CERTIFIED is set. In other case user can run CAC/beaconing without proper handling of pulse events (without radar detection activated).

2014-03-14ath9k_hw: set ANI firstep as absolute values instead of relativeFelix Fietkau
On older chips, the INI value differ in similar ways as cycpwr_thr1, so convert it to absolute values as well. Since the ANI algorithm is different here compared to the old implementation (fewer steps, controlled at a different point in time), it makes sense to use values similar to what would be applied for newer chips, just without relying on INI defaults.

2014-03-14ath9k_hw: set ANI cycpwr_thr1 as absolute values instead of relativeFelix Fietkau
The table was copied from the ANI implementation of AR9300. It assumes that the INI values contain a baseline value that is usable as reference from which to increase/decrease based on the noise immunity value. On older chips, the differences are bigger and especially AR5008/AR9001 are configured to much more sensitive values than what is useful. Improve ANI behavior by reverting to the absolute values used in the previous implementation (expressed as a simple formula instead of the old table).

2014-03-14ath9k_hw: remove ANI function restrictions for AP modeFelix Fietkau
The primary purpose of this piece of code was to selectively disable OFDM weak signal detection. The checks for this are elsewhere, and an earlier commit relaxed the restrictions for older chips, which are more sensitive to interference.

2014-03-14ath9k: fix ready time of the multicast buffer queueFelix Fietkau
qi->tqi_readyTime is written directly to registers that expect microseconds as unit instead of TU. When setting the CABQ ready time, cur_conf->beacon_interval is in TU, so convert it to microseconds before passing it to ath9k_hw. This should hopefully fix some Tx DMA issues with buffered multicast frames in AP mode. Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2014-03-13ath9k: Fix sequence number assignment for non-data framesHelmut Schaa
Since commit 558ff225de80ac95b132d3a115ddadcd64498b4f (ath9k: fix ps-poll responses under a-mpdu sessions) non-data frames would have gotten a sequence number from a TIDs sequence counter instead of using the global sequence counter. This can lead to instable connections. To fix this only select the correct TID if we are processing a data frame. Furthermore, prevent non-data frames to get a sequence number from a TID sequence counter by adding a check to ath_tx_setup_buffer.

2014-03-03ath9k_hw: tweak noise immunity thresholds for older chipsetsFelix Fietkau
Older chipsets are more sensitive to high PHY error counts, and the current noise immunity thresholds were based on tests run at QCA with newer chipsets. This patch brings back the values from the old ANI implementation for old chipsets, and it also disables weak signal detection on an earlier noise immunity level, to improve overall radio stability on affected devices.

2014-03-03ath9k_hw: toggle weak signal detection in AP mode on older chipsetsFelix Fietkau
The commit 80b4205b "ath9k: Fix OFDM weak signal detection for AP mode" prevented weak signal detection changes from taking effect in AP mode on all chipsets, claiming it is "not allowed". The main reason for not disabling weak signal detection in AP mode is that typically beacon RSSI is used to track whether it is needed to boost range, and this is unavailable in AP mode for obvious reasons. The problem with not disabling weak signal detection is that older chipsets are very sensitive to high PHY error counts. When faced with heavy noise, this can lead to an excessive amount of "Failed to stop TX DMA" errors in the field. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
