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?

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.
