Wait, what happened here? You can't remove old API.

Here is my intention is to make the unique average ack signal and last ack signal support in station dump irrespective of data or management tx ack packet.
Do you want me to add a new API for management tx ack packet?

Same here, why are you removing the data-ack-signal API?

Is that just a rebase error or something?

Or is it intentional, but then please explain what you're trying to do
and I can help find a correct solutions.

Here i renamed above API because in driver i will fill this "NL80211_EXT_FEATURE_ACK_SIGNAL_SUPPORT" if firmware supports either of the one "WMI_SERVICE_TX_DATA_ACK_RSSI" or "WMI_SERVICE_HTT_MGMT_TX_COMP_VALID_FLAGS".
This is to make unique avg ack signal/last ack signal support.

Balaji.
