The only way to configure the number of VFs continues to be through
the max_vfs module parameter.  I've got a patch to do it through
ethtool sitting on the back burner but due to other requirements of
my day job I've not been able to work on it since last fall.

Hi Ben,

If I want to pick the RFCs and add support for configuring the number
of VFs - do you think ethtool's the right place for such added
support?

I'm asking since as far as I can see, ethtool (today) doesn't contain
any features related to virtual functions.

I think a PCI utility tool would be better, SR-IOV is not limited to
network devices.  That's one of the reasons I dropped the RFC.  I
haven't gotten back to the idea since then due to my day job keeping me
pretty busy.

For what it's worth, I agree with this.

I'd love to have the ability to set the number of VFs on the fly.   From my perspective it would be ideal if this could be exported via /sys or something rather than a standalone tool using a binary API.  It's fewer packages for userspace to deal with as well as being easily scripted.
