Toshiaki Makita d397b9682c veth: Add ethtool statistics support for XDP ...

Expose per-queue stats for ethtool -S.
As there are only rx queues, and rx queues are used only when XDP is
used, per-queue counters are only rx XDP ones.

Example:

$ ethtool -S veth0
NIC statistics:
     peer_ifindex: 11
     rx_queue_0_xdp_packets: 28601434
     rx_queue_0_xdp_bytes: 1716086040
     rx_queue_0_xdp_drops: 28601434
     rx_queue_1_xdp_packets: 17873050
     rx_queue_1_xdp_bytes: 1072383000
     rx_queue_1_xdp_drops: 17873050
