[dpdk-dev] [PATCH v3] doc: add a restriction to multi-process support

[Junjie Chen <junjie.j.chen@intel.com>]

This patch add a restriction to multi-process support: secondary
processes should only run alongside primary process with same DPDK
version, so that secondary processes can use the same hugepage mmap
layout as primary process.
