dummy driver was extended with VF-related netdev APIs for testing SR-IOV-related software. netdevsim did not exist back then. Implement SR-IOV functionality in netdevsim. Notable difference is that since netdevsim has no module parameters, we will actually create a device with sriov_numvfs attribute for each netdev. The zero MAC address is accepted as some HW use it to mean any address is allowed. Link state is also now validated.
