The CONVERGED_TDLS_ENABLE feature flag was originally introduced when the TDLS feature was being componentized so that one could select either the legacy implementation or the componentized implementation. That componentization activity has concluded and the legacy implementation no longer exists. To align with the current usage switch to exclusively using the FEATURE_WLAN_TDLS feature flag since that more accurately describes the code being protected.
