Hi Wan,
Sorry for the delay in the review.
I've started looking at this patch. Please see some initial comments below. I'll
continue on Monday.
Thanks.

put dump-meters' result in one line so add-meters can handle.
save and restore meters when restart ovs.
bundle functions are not implemented in this patch.

v3:
add '--oneline' option for dump-meter(s) command
v2:
fix failed testcases, as dump-meters format changes

For the sake of consistency across all the commands, I would either omit the

For the documentation (ovs-ofctl(8)), I would also put it before (similar to how
group commands are documented).
