From 0eeba58a2a5273b5f9dd95d3e219a2d4ad003244 Mon Sep 17 00:00:00 2001
From: Honggang Li <honli@redhat.com>
Date: Mon, 11 Jan 2021 16:59:08 +0800
Subject: [PATCH] Check PCIe relaxed ordering compliant
Significantly performance degradation may be observed when PICe
relaxed ordering enabled over CPU which is not PCIe RO compliant.
Emit a warning message for such scenario.
