45 * @usr_handle: pointer to additional user-defined information about bearer
46 * @mtu: max packet size bearer can support
47 * @blocked: non-zero if bearer is blocked
48 * @lock: spinlock for controlling access to bearer

50 * @name: bearer name (format = media:interface)
52 * Note: TIPC initializes "name" and "lock" fields; user is responsible for
53 * initialization all other fields when a bearer is enabled.
