Drivers: hv: vmbus: Support per-channel driver state
As we implement Virtual Receive Side Scaling on the networking side
(the VRSS patches are currently under review), it will be useful to have
per-channel state that vmbus drivers can manage. Add support for
managing per-channel state.

KY:
Do you know the original tree this patch was checked into by Greg KH? Or,
did Greg checked into linux-next tree directly?

Thanks,
- Haiyang
