+ * enum batadv_tt_client_flags - TT client specific flags
+ * @BATADV_TT_CLIENT_DEL: the client has to be deleted from the table
+ * @BATADV_TT_CLIENT_ROAM: the client roamed to/from another node and the new
+ *  update telling its new real location has not been received/sent yet
+ * @BATADV_TT_CLIENT_WIFI: this client is connected through a wifi interface.
+ *  This information is used by the "AP Isolation" feature
+ * @BATADV_TT_CLIENT_ISOLA: this client is considered "isolated". This
+ *  information is used by the Extended Isolation feature
+ * @BATADV_TT_CLIENT_NOPURGE: this client should never be removed from the table
+ * @BATADV_TT_CLIENT_NEW: this client has been added to the local table but has
+ *  not been announced yet
+ * @BATADV_TT_CLIENT_PENDING: this client is marked for removal but it is kept
+ *  in the table for one more originator interval for consistency purposes
+ * @BATADV_TT_CLIENT_TEMP: this global client has been detected to be part of
+ *  the network but no nnode has already announced it
+ *
+ * Bits from 0 to 7 are called _remote flags_ because they are sent on the wire.
+ * Bits from 8 to 15 are called _local flags_ because they are used for local
+ * computations only.
+ *
+ * Bits from 4 to 7 - a subset of remote flags - are ensured to be in sync with
+ * the other nodes in the network. To achieve this goal these flags are included
+ * in the TT CRC computation.
