Introduce TWT action frames parsing support to mac80211. Currently just individual TWT agreement are support in AP mode. Whenever the AP receives a TWT action frame from an associated client, after performing sanity checks, it will notify the underlay driver with requested parameters in order to check if they are supported and if there is enough room for a new agreement. The hw is expected to set agreement result and report it to mac80211. The two following drv callbacks have been added to mac80211: - add_twt_setup (mandatory) - twt_teardown_request (optional) mac80211 will send an action frame reply according to the result reported by the driver/fw. Add individual TWT support to mt7915 in AP mode. Changes since v4: - drop mac80211 patches since they are already applied - fix table_id configuration Changes since v3: - move twt_setup status management in ieee80211_report_used_skb() in order to consider when the driver drops the frame on the tx path - minor changes Changes since v2: - introduce status_queue for twt status frame parsing - add tracing for add_twt_setup/twt_teardown_request - fix routine naming convention - always reply with reject frames for broadcast agrt requests Changes since v1: - fix rcu unbalance in mt7915/debugfs.c Changes since rfc: - run ieee80211_s1g_status_h_twt only for failed twt action frames - change add_twt_setup return value from int to void Lorenzo Bianconi (5): mt76: mt7915: introduce __mt7915_get_tsf routine mt76: mt7915: introduce mt7915_mcu_twt_agrt_update mcu command mt76: mt7915: introduce mt7915_mac_add_twt_setup routine mt76: mt7915: enable twt responder capability mt76: mt7915: add twt_stats knob in debugfs .../wireless/mediatek/mt76/mt7915/debugfs.c | 28 +++ .../net/wireless/mediatek/mt76/mt7915/init.c | 3 + .../net/wireless/mediatek/mt76/mt7915/mac.c | 179 ++++++++++++++++++ .../net/wireless/mediatek/mt76/mt7915/main.c | 39 +++- .../net/wireless/mediatek/mt76/mt7915/mcu.c | 50 +++++ .../net/wireless/mediatek/mt76/mt7915/mcu.h | 9 + .../wireless/mediatek/mt76/mt7915/mt7915.h | 42 +++- 7 files changed, 344 insertions(+), 6 deletions(-) -- 2.31.1
