I think the issue is that any class of PCI device could theoretically
support SR-IOV. For example there could be a storage controller out
there that supports spawning VFs, and an ethtool solution wouldn't work
for a device like that. Personally what I would like to see is a
solution that is more focused on the PCI side of the network adapters
instead of the network side when it comes to enabling VFs.
Thanks,
Alex
