Thanks

Based on Patrick feedback, I believe we can add this followup too

[PATCH net-next-2.6] bnx2x: Dont update vlan_features in bnx2x_set_tso()

Patrick said : "vlan_features doesn't need to be updated, the resulting
dev->features of the VLAN device is computed as the intersection of
dev->features and dev->vlan_features."
