Subject: [PATCH v2 net-next 13/26] veth: drop 'xdp_' suffix from packets and bytes stats
They get updated not only on XDP path. Moreover, packet counter
stores the total number of frames, not only the ones passed to
bpf_prog_run_xdp(), so it's rather confusing.
Drop the xdp_ suffix from both of them to not mix XDP-only stats
with the general ones.
