This comes from an end-user request, where they're running multiple VMs on
hosts with bonded interfaces connected to some interest switch topologies,
where 802.3ad isn't an option. They're currently running a proprietary
solution that effectively achieves load-balancing of VMs and bandwidth
utilization improvements with a similar form of transmission algorithm.

Basically, each VM has it's own vlan, so it always sends its traffic out
the same interface, unless that interface fails. Traffic gets split
between the interfaces, maintaining a consistent path, with failover still
available if an interface goes down.

This has been rudimetarily tested to provide similar results, suitable for
them to use to move off their current proprietary solution.

Still on the TODO list, if these even looks sane to begin with, is
fleshing out Documentation/networking/bonding.rst.

Jarod, did you consider using team driver instead ? :)

That's actually one of the things that was suggested, since team I believe
already has support for this, but the user really wants to use bonding.
We're finding that a lot of users really still prefer bonding over team.
