> When flashing a new firmware image onto the device, the pldmfw library
> parses the image contents looking for a matching record. If no record can be
> found, the function reports an error of -ENOENT. This can produce a very
> confusing error message and experience for the user:
>
> $devlink dev flash pci/0000:ab:00.0 file image.bin
> devlink answers: No such file or directory
>
> This is because the ENOENT error code is interpreted as a missing file or
> directory. The pldmfw library does not have direct access to the extack
> pointer as it is generic and non-netdevice specific. The only way that ENOENT
> is returned by the pldmfw library is when no record matches.
>
> Catch this specific error and report a suitable extended ack message:
>
> $devlink dev flash pci/0000:ab:00.0 file image.bin
> Error: ice: Firmware image has no record matching this device
> devlink answers: No such file or directory
>
> In addition, ensure that we log an error message to the console whenever
> this function fails. Because our driver specific PLDM operation functions
> potentially set the extended ACK message, avoid overwriting this with a
> generic message.
>
> This change should result in an improved experience when attempting to
> flash an image that does not have a compatible record.
