Exactly *what* provisioning system tries to set the VF_MAC on an IPoIB

The provisioning system need not be fully aware in all their
components this is IB here, there's PCI linkage that tells these are
VFs of this PF and they have to be used for these VMs.

along with the fully IB aware solution where the
upper level does provision IB GUIDs.

There has never been upstream support for this MAC->GUID stuff you refer
to.  I'm not convinced we should add it now versus just doing things
right, period.

We **are** doing things right with the new ndo.

Using the small MAC->GUID addition, people could be using non-modified
(or almost non-modified) provisioning systems that assign SRIOV VMs
with a MACs --- just use these patches on their hosts and get DHCP
server supplying IP addresses based on the derived GUIDs (this is
supported today).
