It is reported that those VFs share their RSS configuration with PF and,
thus, they cannot be configured independently.
Also:
- add missing opt_rss.h to if_ixv.c, otherwise RSS kernel option could
not be seen
- do not enable IXGBE_FEATURE_RSS on the older VFs
- set flowid / hash type to M_HASHTYPE_NONE or M_HASHTYPE_OPAQUE_HASH
(based on what the hardware reports) if IXGBE_FEATURE_RSS is not set
