Above parameters will be used by Firmware to do EMLSR operation such as sending EML operation mode notification frame, initial control frame etc. Obtain above parameters from EML capabilities information present in ieee80211_sta object and update the same to Firmware in peer assoc WMI command sent for ML station. MLO is not enabled in WCN7850 and hence this change is not applicable to it as of now. This can be a leverage once it is enabled in future.
