niu: Recognise original ethtool class code for AH/ESP flow hashing
When the RX network flow classification interface was originally defined for reporting and controlling of flow hashing, AH and ESP were not given distinct flow class codes (apparently because the Sun Neptune hardware treats them very similarly). For flow steering, they must be distinguished, so new and separate flow class codes were added for AH and ESP. But for backward- compatibility, flow hash operations should continue to support the original class codes. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.
