Hi Stephen, thanks for taking care of this.

FYI, patch directed to iproute2 or iproute2-next tree should:
- preferrably have [PATCH iproute2] in their subject
- be directed or cc'd to iproute2 maintainers Stephen Hemminger and
  David Ahern, and to the author of the fixed commit if possible.

This should include a Fixes: line on the commit changing val to __u64:
Fixes: 5a52102b7c8f ("ifstat: Add extended statistics to ifstat")
Stephen, David: do Stephen needs to resend this?

That said, patch looks good to me, so feel free to add my reviewed-by to
the following versions of this patch.
