netdev->features is how you should implement your patch, please don't
create new facilities.

With netdev->features they can be validated against netdev->hw_features
which, in this case, r8169 would have this feature bit clear.

That's how all of this stuff is designed to work, the driver says what
the hardware can do and thus ethtool generically can validate attempts
to turn on features.

No new facilities are necessary at all.
