So, if my understanding is correct (and I am not a coder or developer so I may be about to humiliate myself with my ignorance here, but please bear with me for a minute) the infrastructure has been added to net80211 via the new ieee80211_notify_dtim() function, but it's up to the individual drivers e.g. ral(4) to call this function appropriately to enable Power Save Polling in HostAP mode? Or am I way of the track?
I'm just trying to evaluate if it's worth maintaining my OpenBSD access point or look to other options (e.g. a COTS access point with PSP implemented, bridged to the OpenBSD host via ethernet)? I know there are at least a few other people subscribed to this list who have implemented OpenBSD as a wifi access point, some in quite "open" environments e.g. universities - how are they coping? Many thanks to all who are bearing my whining here!
