/* ---------- Done List ---------- */
/* The done list entry opcode field is defined below.
 * The mnemonic encoding and meaning is as follows:
 * TC - Task Complete, status was received and acknowledged
 * TF - Task Failed, indicates an error prior to receiving acknowledgment
 *   for the command:
 *   - no conn,
 *   - NACK or R_ERR received in response to this command,
 *   - credit blocked or not available, or in the case of SMP request,
 *   - no SMP response was received.
 *   In these four cases it is known that the target didn't receive the
 *   command.
 * TI - Task Interrupted, error after the command was acknowledged.  It is
 *   known that the command was received by the target.
 * TU - Task Unacked, command was transmitted but neither ACK (R_OK) nor NAK
 *   (R_ERR) was received due to loss of signal, broken connection, loss of
 *   dword sync or other reason.  The application client should send the
 *   appropriate task query.
 * TA - Task Aborted, see TF.
 * _RESP - The completion includes an empty buffer containing status.
 * TO - Timeout.
