Hi David,

Glad to see we are close to have this feature integrated.

I've just looked into few details before pushing.
One of them are the comments. In mempool they were all ended by a dot.
Please check the new comments.

The doc/guides/rel_notes/deprecation.rst must be updated to remove
the deprecation notice in this patch.

Isn't there some explanations to add in
doc/guides/prog_guide/mempool_lib.rst?

Isn't there a better name than "default" for the default implementation?
I don't think the filename rte_mempool_default.c is meaningful.

The parameter name and its description are not correct.

You can check the doc with doxygen:
	make doc-api-html

Why this empty line?

Please keep it in alphabetical order.
It seems the order was not respected before in mempool.
