    mac80211: inform the driver about update of dtim_period · c65dd147

    Currently, when the driver requires the DTIM period,
    mac80211 will wait to hear a beacon before association.
    This behavior is suboptimal since some drivers may be
    able to deal with knowing the DTIM period after the
    association, if they get it at all.
    
    To address this, notify the drivers with bss_info_changed
    with the new BSS_CHANGED_DTIM_PERIOD flag when the DTIM
    becomes known. This might be when changing to associated,
    or later when the entire association was done with only
    probe response information.
    
    Rename the hardware flag for the current behaviour to
    IEEE80211_HW_NEED_DTIM_BEFORE_ASSOC to more accurately
    reflect its behaviour. IEEE80211_HW_NEED_DTIM_PERIOD is
    no longer accurate as all drivers get the DTIM period
    now, just not before association.
