This looks pretty verbose and harder than necessary format to parse..
Why not simply return UNSUPPORTED/INTERNAL/EXTERNAL? In addition, this
information is available from wpa_s->drv_flags
(WPA_DRIVER_FLAGS_TDLS_SUPPORT and WPA_DRIVER_FLAGS_TDLS_EXTERNAL_SETUP
bits), so there is no need to add the new wpa_tdls_is_supported()
wrapper function (the core wpa_supplicant code sets that
sm->tdls_supported based on drv_flags anyway).
