We should be able to sync it to 1 beacon interval, it seems?

True, but then you'd still technically have a single point where the switch can happen, without missing a beat (beacon) > > AP/GO-follows-STA I can also see, due to regulatory and concurrent > > BSS/P2P usage. > > > > As for those other cases, are they really relevant? > > I think I lost track of the point of the discussion at some point :-) > Weren't we discussing csa_active? :) johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
