crypto: cavium/nitrox - updated debugfs information.
Updated debugfs to provide device partname and frequency etc. New file "stats" shows the number of requests posted, dropped and completed. Signed-off-by: Srikanth Jampala <Jampala.Srikanth@cavium.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
