Hi Hrvoje;

I guess this is your first patch to dpdk.org, here are some suggestions when you send bug fixes;

- When sending fixes, please use "fix" word in the subject line, e.g- rte_sched: fix subport memory leak
- The commit message should include commit id corresponding to the line that you fixes as shown below for this case. 
   Fixes: d9213b829a31 ("sched: remove pipe params config from port level")

Patch looks good to me.

OK, noted, thank you.

Great.

As s side note, it would be nice if this could be backported to 19.11 LTS.
