Subject: [PATCH 2/3] vDPA/ifcvf: enable Intel C5000X-PL virtio-net for vDPA

This commit enabled Intel FPGA SmartNIC C5000X-PL virtio-net
for vDPA.
C5000X-PL vendor id 0x1AF4, device id 0x1000,
subvendor id 0x8086, sub device id 0x0001

To distinguish C5000X-PL from other ifcvf driven devices,
the original ifcvf device is named "N3000".
