sfc: don't report RX hash keys to ethtool when RSS wasn't enabled
If we failed to set up RSS on EF10 (e.g. because firmware declared RX_RSS_LIMITED), ethtool --show-nfc $dev rx-flow-hash ... should report no fields, rather than confusingly reporting what fields we _would_ be hashing on if RSS was working. Fixes: dcb4123cbec0 ("sfc: disable RSS when unsupported") Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
