    mac80211: add PS flag to bss_conf · ab095877
    Eliad Peller authored
    Currently, ps mode is indicated per device (rather than
    per interface), which doesn't make a lot of sense.
    Moreover, there are subtle bugs caused by the inability
    to indicate ps change along with other changes
    (e.g. when the AP deauth us, we'd like to indicate
    CHANGED_PS | CHANGED_ASSOC, as changing PS before
    notifying about disassociation will result in null-packets
    being sent (if IEEE80211_HW_SUPPORTS_DYNAMIC_PS) while
    the sta is already disconnected.)
    Keep the current per-device notifications, and add
    parallel per-vif notifications.
    In order to keep it simple, the per-device ps and
    the per-vif ps are orthogonal - the per-vif ps
    configuration is determined only by the user
    configuration (enable/disable) and the connection
    state, and is not affected by other vifs state and
    (temporary) dynamic_ps/offchannel operations
    (unlike per-device ps).
