 * enum batadv_tt_client_flags - TT client specific flags

 * @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.
