Subject: [PATCH] PCI: altera: Fix TLP completion status
Date: Fri, 17 Feb 2017 08:27:10 +0800 [thread overview]
Message-ID: <1487291230-21495-2-git-send-email-yadi.hu@windriver.com> (raw)
In-Reply-To: <1487291230-21495-1-git-send-email-yadi.hu@windriver.com>
From: "Hu Yadi" <yadi.hu@windriver.com>
the driver does not use exactly 'Completion Status' value in TLP,
these bits should be b15:13 not b14:12.
