stmmac_dev_probe doesn't propagate feature flags to VLANs. So features
like offloading don't correspond with the general features and it's not
possible to manipulate features via ethtool -K to affect VLANs.
Propagate feature flags to vlan features. Drop TSO feature because
it does not work on VLANs yet.
