[ovs-dev] plan to integrate Hyper-V support

[Nithin Raju]

hi Ben,
This is very reasonable. This will enable meaningful collaboration
without duplicating effort. There are some indications of design choices
that have seem different between the two implementations. Discussing
about those things would be useful for the product.

For Eg:.

The "Windows support daemon" and the "Persistent port naming" have some
overlapping functionality. We can discuss and figure out what is the best
approach.

Absolutely.

thanks!
