I like seeing a better solution to hot plug. But it is worth mentioning that for the Hyper-V netvsc driver this is mostly unnecessary. The Hyper-V host notifies the network driver directly about availability of SRIOV device, and the netvsc device driver can use that to do its own VF management. It doesn't really need (or want) to be using a general PCI solution.
