From deedc8d9913e6dfe8d77a69860290b5e058e44ca Mon Sep 17 00:00:00 2001 From: Junjie Chen Date: Wed, 29 Nov 2017 12:17:13 -0500 Subject: [PATCH] doc: add a restriction to multi-process support 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.
