We have got basic radar detection part working. It has been tested with software based pulse simulator. The question is on how to integrate it with mac80211. Pulse detection has to be done deep in specific driver but decision making can be shifted to either mac80211 or higher into user space. Current ETSI specification allows up to 1 second time for changing channel so it doesn't need to be real time. Has anyone put already some thoughts on where to implement available channel list management, radar table handling, etc. and what would be the interface?
