batman-adv: improve the TT flags documentation
Convert the current documentation for the TT flags in proper kerneldoc and improve it by adding an explanation for each of the flags. Signed-off-by: Antonio Quartulli <antonio@open-mesh.com> Signed-off-by: Marek Lindner <mareklindner@neomailbox.ch>

+ * 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.
