About the title, what is "rte API"?
I guess you mean DPDK API with rte prefix.
But given all DPDK API have rte prefix,
and this patch is for DPDK,
you can just say "API".
So the title can be:
ethdev: modify API for single flow dump
But it can look as single flow dump was possible before,
which is wrong because it is a new feature.
Another idea is wrong:
The packets of the flow are not dumped,
it is only dumping the HW representation of the flow rule.
I propose to simply describe the new feature:
ethdev: dump single flow rule
> + * @param[in] flow
> + * The pointer of rte flow.
Please replace "rte flow" with 'flow rule".
Is it allowed to pass NULL? Will it dump all?
If yes, you can change to:
Flow rule to dump.
Dump all rules if NULL.
