Subject: [PATCH] 203-mac80211-ath11k-fw-dynamic-muedca.patch
mac80211/ath11k:FW Initiated Dynamic MU-EDCA
Implementing the updating of firmware initiated dynamic MU-EDCA
parameters in Beacon IE. Firmware routinely checks its clients and
updates its MU-EDCA values every 3 seconds. Firmware is tuning
MU-EDCA parameters to improve performance. As part of this process,
the firmware informs host about new MU-EDCA values utilizing
WMI_MUEDCA_PARAMS_CONFIG_EVENTID. FW expectation is that host will
update MU-EDCA parameters in the Beacon IE.
Implementation consists of:
(1) Receiving updated parameters through event in ATH11k
(2) Passing updated parameters ATH11k -> mac80211 -> cfg80211
(3) Passing updated parameters to user space.
