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. 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, add it to a local linked list. * Cancel the ongoing CAC. * If number of contexts found marked with radar is more than one and if the wiphy does not support MLO flag, throw a warning and return. * Process the local linked list and call the radar event for each entry. 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.
