IB/opa-vnic: Virtual Network Interface Controller (VNIC) netdev 



OPA VNIC netdev function supports Ethernet functionality over Omni-Path
fabric by encapsulating Ethernet packets inside Omni-Path packet header.
It allocates a rdma netdev device and interfaces with the network stack to
provide standard Ethernet network interfaces. It overrides HFI1 device's
netdev operations where it is required.
