[PATCH v2 0/2] wifi: mac80211: Power-save state and TIM handling fixes

[Lee Jones <lee@kernel.org>]

Following up on the v1 discussion [0], this two-patch series:

 1. Makes AP-side Power Management (PM) bit handling in
    ieee80211_rx_h_sta_process() symmetric across both wake-to-doze and
    doze-to-wake transitions, ignoring the reserved PM bit in
    non-bufferable management frames while still waking sleeping
    stations on Authentication and (Re)Association Request frames per
    commit 9fef65443388 ("mac80211: always update the PM state of a peer
    on MGMT / DATA frames").

 2. Ensures an awake client station sends a wake nullfunc frame in
    ieee80211_rx_mgmt_beacon() when the Beacon TIM element indicates
    buffered unicast traffic for its AID, even when dynamic power-save
    is disabled (dynamic_ps_timeout == 0) and IEEE80211_CONF_PS is not
    set.

v1 => v2:
 - Make non-bufferable MMPDU PM-bit handling symmetric in both
   directions and expand the commit description.
 - Add client-side wake nullfunc transmission in
   ieee80211_rx_mgmt_beacon() when the TIM bit is set while awake.
