Yes, and then there are 'other network' controllers too ... IB which I don't know if it adheres to ethtool, since it's not an Ethernet device ... isn't that why they call it Infiniband ... ;-) )
In the telecom space, they use NTBs and PCI as a 'network' ... I know, not common in Linux space, and VFs in that space aren't being discussed (that I've ever heard), but another example where 'network' != Ethernet, so ethtool doesn't solve PCI-level configuration/use.
So, VFs are a PCI defined entity, so their enable/disablement should be handled by PCI.
Conversely, when dealing with networking attributes of a PCI-VF ethernet-nic, networking tools should be used, not PCI tools.
