Could you at least make some common code that is shared in between
netvsc and virtio_net so this is handled in exacly the same way in both?

IMHO netvsc is a vendor specific driver which made a mistake on what
behaviour it provides (or tried to align itself with Windows SR-IOV).
Let's not make a far, far more commonly deployed and important driver
(virtio) bug-compatible with netvsc.

To Jiri's initial comments, I feel the same way, in fact I've talked to
the NetworkManager guys to get auto-bonding based on MACs handled in
user space.  I think it may very well get done in next versions of NM,
but isn't done yet.  Stephen also raised the point that not everybody is
using NM.
