Automatic bonding of VFs and virtio

[Jakub Kicinski <kubakici wp pl>]

Hi!

There is a real need to automatically instantiate a bond/team and
enslave a VF and virtio device to solve live migrations issues [2].  
This has been tackled in multiple ways, but I believe this would be
a great feature to have in NetworkManager.  The recent proposal was 
to simply detect that bond should be created based on MAC addresses
of the virtio and VF devices being identical [1].

Is this a feature worth considering?  Any thoughts, comments?
