[dpdk-dev] [PATCH] librte_cfgfile: add section num entries by index

[Guduri Prathyusha]

rte_cfgfile_section_num_entries_by_index() is added to get the number of
entries of a section when multiple sections of the same name are
present.

Cristian, this is an old patch not reviewed.
Any comment please?

Do you need this reviewed for this release, or can it wait until the next release?

I have a few patches on my list to review (librte_cfgfile, librte_sched), I will make this review a priority for next release cycle.

It has already waited 3 months without any ping, so I guess it can wait.

OK thanks.
It's not about you specifically, but as a community, we need to improve
our response time (I'm not good as well).

I don't like the fact that the section name is being overwritten here,
but the behaviour is consistent with that done by the other "by_index()"
functions, so it's probably better to keep this.
In future a change to consider would be remove the sectionname entirely
from the function arguments since it serves no purpose that I can see.

I agree that sectionname doesn't serve any purpose and can be removed. Thanks.
