   Target release for removal of the legacy API will be defined once most

-* eal: In v18.11 ``rte_eal_dev_attach()`` and ``rte_eal_dev_detach()``

-  Hotplug functions ``rte_eal_hotplug_add()`` and ``rte_eal_hotplug_remove()``

 * pdump: As we changed to use generic IPC, some changes in APIs and structure
   are expected in subsequent release.
