wifi: cfg80211: Extend cfg80211_new_sta() for MLD AP
Add support for drivers to indicate STA connection(MLO/non-MLO) when user space SME (e.g., hostapd) is not used for MLD AP. Add new parameters in struct station_info to provide below information in cfg80211_new_sta() call: - MLO link ID of the AP, with which station completed (re)association. This is applicable for both MLO and non-MLO station connections when the AP affiliated with an MLD. - Station's MLD address if the connection is MLO capable. - (Re)Association Response IEs sent to the station. User space needs this to determine rejected and accepted affiliated links information of the connected station if the connection is MLO capable.
