    58	 * @opcode    -  roce slow path opcode
    59	 *
    60	 * In some cases like firmware halt is detected, the driver is supposed to
    61	 * remap the error code of the timed out command.
    62	 *
    63	 * It is not safe to assume hardware is really inactive so certain opcodes
    64	 * like destroy qp etc are not safe to be returned success, but this function
    65	 * will be called when FW already reports a timeout. This would be possible
    66	 * only when FW crashes and resets. This will clear all the HW resources.
    67	 *
    68	 * Returns:
    69	 * 0 to communicate success to caller.
    70	 * Non zero error code to communicate failure to caller.
