/* BATADV_TT_CLIENT flags.
* Flags from BIT(0) to BIT(7) are sent on the wire, while flags from BIT(8) to
* BIT(15) are used for local computation only.
* Flags from BIT(4) to BIT(7) are kept in sync with the rest of the network.
/**
* 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.
