ionic: support sr-iov operations
Add the netdev ops for managing VFs. Since most of the
management work happens in the NIC firmware, the driver becomes
mostly a pass-through for the network stack commands that want
to control and configure the VFs.
We also tweak ionic_station_set() a little to allow for
the VFs that start off with a zero'd mac address.
