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. To fix this, keep track of the final status in the queue object and use it when completing the request. The new member can be placed adjacent to the receive related members and fits in the cacheline as there is a 4 byte hole. Signed-off-by: Daniel Wagner <redacted> ---
