Currently, the ACK RSSI value is not shown in station dump. Enable WMI
resource flag for ACK RSSI in WMI INIT command to add ACK RSSI value in
management TX completion event from WMI. Update ACK RSSI value obtained
in management and data frame completion path to ieee80211_tx_info. Also
advertise NL80211_EXT_FEATURE_ACK_SIGNAL_SUPPORT flag during hardware
register to mac80211 layer so that ACK RSSI is added to station dump
message.

Example output :

Hello,
It seems this ppdu_id is retrieved from frimware but not used in this patchset
Is this by design ?
