Hi Rahul,
You need to strip the __rte_experimental attribute in the header file also.

That's what I first thought... but those are variables, and there were
not marked in the header.
At least, those symbols must be alphabetically sorted in version.map.
About checking for experimental mark on variables... I had a patch,
but never got it in.
I think we should instead (forbid such exports and|insist on) rework
API / libraries that rely on public variables.

My mistake - should have checked.

I'll pull together a script to identify all the variables in DPDK.
Are you expecting the rework on the port api to be done prior to 21.11?

Does it mean we should not promote these variables?

So the net-net is that variables are almost impossible to version.
Think about maintaining two parallel versions of the same variable, and having to track and reconcile state between them.
So variables are make ABI versioning (and maintenance) harder, and are best avoided.
In this particular case.
I would suggest leaving these as experimental and improving the API, post 21.11.
