+ * @BATADV_TT_CLIENT_WIFI: this client is connected through a wifi interface.
+ * This information is used by the "AP Isolation" feature

+ * @BATADV_TT_CLIENT_NOPURGE: this client should never be removed from the table

+ * @BATADV_TT_CLIENT_PENDING: this client is marked for removal but it is kept
