    cfg80211: Allow TDLS peer AID to be configured for VHT · 5e4b6f56

    VHT uses peer AID in the PARTIAL_AID field in TDLS frames. The current
    design for TDLS is to first add a dummy STA entry before completing TDLS
    Setup and then update information on this STA entry based on what was
    received from the peer during the setup exchange.
    
    In theory, this could use NL80211_ATTR_STA_AID to set the peer AID just
    like this is used in AP mode to set the AID of an association station.
    However, existing cfg80211 validation rules prevent this attribute from
    being used with set_station operation. To avoid interoperability issues
    between different kernel and user space version combinations, introduce
    a new nl80211 attribute for the purpose of setting TDLS peer AID. This
    attribute can be used in both the new_station and set_station
    operations. It is not supposed to be allowed to change the AID value
    during the lifetime of the STA entry, but that validation is left for
    drivers to do in the change_station callback.
