SUNRPC: Add RFC 8009 checksum KUnit tests
RFC 8009 provides sample checksum results. Add KUnit tests to ensure our implementation derives the expected results for the provided sample input. Tested-by: Scott Mayhew <smayhew@redhat.com> Reviewed-by: Simo Sorce <simo@redhat.com> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
