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. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S.
