When using RSS, frames might not be processed in the correct order, and thus AP_LINK_PS must be used; most likely with firmware keeping track of the powersave state, this is the case in iwlwifi now. In this case, the driver can use ieee80211_sta_ps_transition() to still have mac80211 manage powersave buffering. However, for U-APSD and PS-Poll this isn't sufficient. If the device can't manage that entirely on its own, mac80211's code should be used. To allow this, export two functions: ieee80211_sta_uapsd_trigger() and ieee80211_sta_pspoll().
