From 28a2568f469d9d715b9dfbafdce14537e35b7d4e Mon Sep 17 00:00:00 2001 From: Xiaoyun Li Date: Wed, 25 Dec 2019 17:09:42 +0800 Subject: [PATCH] examples/ntb: fix mempool ops setting Mempool ops may register in different order when compiling. The default ops index is always zero but the wanted ops is ring_mp_mc. This patch sets best mempool ops before generating mbuf pool to fix this issue.
