 /**
  * tipc_bearer_send- sends buffer to destination over bearer
  *
- * Returns true (1) if successful, or false (0) if unable to send
- *
  * IMPORTANT:
  * The media send routine must not alter the buffer being passed in
  * as it may be needed for later retransmission!
- *
- * If the media send routine returns a non-zero value (indicating that
- * it was unable to send the buffer), it must:
- *   1) mark the bearer as blocked,
- *   2) call tipc_continue() once the bearer is able to send again.
- * Media types that are unable to meet these two critera must ensure their
- * send routine always returns success -- even if the buffer was not sent --
- * and let TIPC's link code deal with the undelivered message.
