[dpdk-dev] [PATCH] doc: announce API change in mbuf

[Thomas Monjalon <thomas@monjalon.net>]

In order to prepare for a long term stable API, the mbuf library
has to change: allowing more features as dynamic fields,
and fixing the lack of rte_ prefix in the namespace.
The namespace fix should not break the compatibility by keeping
some aliases during few releases to give time for migration.
