netdevsim: add SR-IOV functionality
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.
