Hi, in mac80211's software scan implementation the passive dwell time IEEE80211_PASSIVE_CHANNEL_TIME is set to (HZ / 5) which means we stay 200ms on each passive channel. Compared to iwlwifi's hw scan and the old ipw* drivers which use values around 120ms this is quite long. Reducing the passive dwell time from 200ms to 120ms could save us something around a second on cards capable of 11a and we would be still able to catch beacons from most access points (assuming a ~100ms beacon interval). Objections?
