For this patch and another one about removing rte_cpu_check_supported(),
I have a general comment on the date of removal.

As was stated recently in the contribution guide:
	http://git.dpdk.org/dpdk/commit/?id=7abe4a24cc
	"Deprecated APIs are removed completely just after the next LTS."

The idea behind this policy is to avoid removals during LTS releases,
in order to have at least one release before X.11 LTS for end users
to prepare replacing the usage of the removed API.

Does it make sense to postpone any API removal after 19.11?

Those symbols have been marked as deprecated for a long time.
Users had to either disable Werror or they actually migrated to the new apis.
If they chose the lazy way of not migrating to the new apis, I suspect
they forgot about it and/or they won't look at the release notes.


I don't particularly have a problem with waiting for 20.02, those are
easy to remove anyway.

Yes I agree.
That's why they can be surprised when hitting the removal.
Avoiding this removal in LTS release is one more care for
the lazy users. The question: is too much caution?

My 2c is that if they are have signalled as deprecated since v17.11.
They are fair game for removal at this point.

since it was deprecated in previous LTS, I think it is already OK to remove.
