* eal: new ``numa_node_count`` member will be added to ``rte_config`` structure
in v18.05.
* eal: due to internal data layout reorganization, there will be changes to
several structures and functions as a result of coming changes to support
memory hotplug in v18.05.
``rte_eal_get_physmem_layout`` will be deprecated and removed in subsequent
releases.
``rte_mem_config`` contents will change due to switch to memseg lists.
``rte_memzone`` member ``memseg_id`` will no longer serve any useful purpose
and will be removed.
* ethdev: a new Tx and Rx offload API was introduced on 17.11.
In the new API, offloads are divided into per-port and per-queue offloads.
Offloads are disabled by default and enabled per application request.
