53 * the payload consists of zero or more type/length/value (TLV) items

147 * TLV types defined for TIPC
150 #define TIPC_TLV_NONE 0 /* no TLV present */
151 #define TIPC_TLV_VOID 1 /* empty TLV (0 data bytes)*/
236 * The error string TLV is a null-terminated string describing the cause
242 #define TIPC_CFG_TLV_ERROR "\x80" /* request contains incorrect TLV(s) */
250 /* prototypes TLV structures for proposed commands */
264 * A TLV consists of a descriptor, followed by the TLV value.
265 * TLV descriptor fields are stored in network byte order;
266 * TLV values must also be stored in network byte order (where applicable).
267 * TLV descriptors must be aligned to addresses which are multiple of 4,
268 * so up to 3 bytes of padding may exist at the end of the TLV value area.
269 * There must not be any padding between the TLV descriptor and its value.
