This change will enhance in version number returned. Current version info returned won't be able to be recognized by Linux VF driver, change to values that both DPDK VF and Linux driver can recognize. The expense is original DPDK host specific feature like CFG_VLAN_PVID and CONFIG_VSI_QUEUES_EXT will not available. DPDK VF also can't identify host driver by version number returned. It always assume talking with Linux PF.
