dpdk: change netvsc device port type

Netvsc devices have the port type determined from their link speed.
The link speed between reboots of an Azure VM does not always end
up at the same value, so an interface that was FortyGigabitEthernet0
earlier may be FiftyGigabitEthernet0 now. That makes it difficult
to maintain a persistent store of configurations and apply those at
startup.

Change the port type to be VF so the name will always be generated
as VirtualFunctionEthernetX.

Type: improvement
