If there is no slaves, should we add the gso_partial_features?
The other partial feature sets are added after 'done:', why not do the same for gso_partial_features for consistency? 'gso_partial_features' is otherwise not set anywhere else and relies on it being set to zero when allocated in alloc_netdev_mqs. I think it's better for it to be explicitly initialized in all cases here, like the other feature sets.
