[dpdk-dev] [PATCH 2/2] net/netvsc: fix ethdev get_supported_ptypes

[Stephen Hemminger]

When doing rte_eth_dev_get_supported_ptypes on netvsc device
the values reported are incorrect if VF is not present.

If no VF is present the device uses rte_net_get_ptype()
which can return a wide range of values. Use the same table
as TAP device in that case.
