Just to be clear, include/net/page_pool.h is still there, we are not
putting page_pool.h in include/net/page_pool/ and renaming it to
something else, right? As there is no that kind of uniformity in
include/net/* as far as I can see.

More specificly, yon means the below, right?
include/net/page_pool.h
include/net/page_pool/types.h
