2024-09-06wifi: mt76: mt7915: add dummy HW offload of IEEE 802.11 fragmentationBenjamin Lin
Currently, CONNAC2 series do not support encryption for fragmented Tx frames. Therefore, add dummy function mt7915_set_frag_threshold() to prevent SW IEEE 802.11 fragmentation.

2024-09-06wifi: mt76: mt7915: reset the device after MCU timeoutFelix Fietkau
On MT7915, MCU hangs do not trigger watchdog interrupts, so they can only be detected through MCU message timeouts. Ensure that the hardware gets restarted when that happens in order to prevent a permanent stuck state.

2024-09-06wifi: mac80211: handle ieee80211_radar_detected() for MLOAditya Kumar Singh
Currently DFS works under assumption there could be only one channel context in the hardware. Hence, drivers just calls the function ieee80211_radar_detected() passing the hardware structure. However, with MLO, this obviously will not work since number of channel contexts will be more than one and hence drivers would need to pass the channel information as well on which the radar is detected. Also, when radar is detected in one of the links, other link's CAC should not be cancelled. Hence, in order to support DFS with MLO, do the following changes - * Add channel context conf pointer as an argument to the function ieee80211_radar_detected(). During MLO, drivers would have to pass on which channel context conf radar is detected. Otherwise, drivers could just pass NULL. * ieee80211_radar_detected() will iterate over all channel contexts present and * if channel context conf is passed, only mark that as radar detected * if NULL is passed, then mark all channel contexts as radar detected * Then as usual, schedule the radar detected work. * In the worker, go over all the contexts again and for all such context which is marked with radar detected, cancel the ongoing CAC by calling ieee80211_dfs_cac_cancel() and then notify cfg80211 via cfg80211_radar_event(). * To cancel the CAC, pass the channel context as well where radar is detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is canceled only on the links using the provided context, leaving other links unaffected. This would also help in scenarios where there is split phy 5 GHz radio, which is capable of DFS channels in both lower and upper band. In this case, simultaneous radars can be detected.
