Use "%u" and a cast as in other places when port ID is formatted.
This fixes -Wformat warning with clang 10.0.0 on Windows.

Fixes: f8244c6399d9 ("ethdev: increase port id range")

how come not just `% " PRIu16 "\n"' ?

what was the -Wformat clang on windows complaint?

PRIx16 would work, but I noticed that in other places where port ID is
printed, the pattern above is used. IMO uniform approach is better.

ah, consistency. yes i'll have some of that. maybe one day in the future
we can change them all in one shot, but not today.

I think PRIu16 is more appropriate.
Consistency doesn't matter if an approach is better.

works for me.

> Consistency doesn't matter if an approach is better.

well, there is some value in having consistency even if it is something
sub-optimal if we intend to do a mechanical change of all instances in
the future.

as a side question, what is the projects stance on getting more warnings
clean? there are a few not enabled that i'd really like to see e.g.
format, conversion, truncation etc..

i looked at lib/eal previously and there are... hundreds? of instances so
it's a non-trivial task. the problem i see is somehow getting to a
warnings clean state where we can enable -Werror in the CI pipeline but
at the same time figuring out how to prevent new instances from
appearing until we do.

I don't understand the question.
We are already supposed to be warning-free,
and -werror should be enabled in all CI labs.
What are the gaps?

NAK

Just use %u  it works for uint16. Don't start using hex, no other places in
DPDK print port number in hex.

Ok, that matches what is used in rte_ethdev.h

with the warnings we have enabled -Werror passes, but we don't have all
the warnings we could have that are of value.  it would be great to see
-Wconversion -Wsign-compare -Wsign-conversion passing clean.

i admit it is a lot of work though.

-Wsign-compare is enabled for sure, look at config/meson.build.
For the conversion warnings, I don't know.
Do not hesitate to propose new warnings enablement
with a list of warnings it is generating in its current state,
so we can decide whether to enable (and fix) or not.
