The spec says 7.4.6.1 Digest Error handling When a host detects a data digest error in a C2HData PDU, that host shall continue processing C2HData PDUs associated with the command and when the command processing has completed, if a successful status was returned by the controller, the host shall fail the command with a non-fatal transport error. Currently the transport is reseted when a data digest error is detected. Instead, when a digest error is detected, mark the final status as NVME_SC_DATA_XFER_ERROR and let the upper layer handle the error. In order to keep track of the final result maintain a status field in nvme_tcp_request object and use it to overwrite the completion queue status (which might be successful even though a digest error has been detected) when completing the request.
