mac80211: use ps-poll when dynamic power save mode is disabled
When a directed tim bit is set, mac80211 currently disables power save ands sends a null frame to the AP. But if dynamic power save is disabled, mac80211 will not enable power save ever gain. Fix this by adding ps-poll functionality to mac80211. When a directed tim bit is set, mac80211 sends a ps-poll frame to the AP and checks for the more data bit in the returned data frames. Using ps-poll is slower than waking up with null frame, but it's saves more power in cases where the traffic is low. Userspace can control if either ps-poll or null wakeup method is used by enabling and disabling dynamic power save. Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W.
