Having a special versioning for experimental/internal libraries put a additional maintenance cost while this status is already announced in MAINTAINERS and the library headers/documentation. Following discussions and vote at 05/20 TB meeting [1], use a single versioning for all libraries in DPDK. Note: for the ABI check, an exception [2] had been added when tweaking this special versioning [3]. Prefer explicit libabigail rules (which will be dropped in 20.11). 1: https://mails.dpdk.org/archives/dev/2020-May/168450.html 2: https://git.dpdk.org/dpdk/commit/?id=23d7ad5db41c 3: https://git.dpdk.org/dpdk/commit/?id=ec2b8cd7ed69 Signed-off-by: David Marchand <david.marchand@redhat.com> Acked-by: Ray Kinsella <mdr@ashroe.eu> Acked-by: Bruce Richardson <bruce.richardson@intel.com>
