Subject: [PATCH v2 10/13] lpfc: Fix nvme embedded io length on new hardware
Date: Tue, 6 Feb 2018 18:28:48 -0800 [thread overview]
Message-ID: <20180207022851.11800-11-jsmart2021@gmail.com> (raw)
In-Reply-To: <20180207022851.11800-1-jsmart2021@gmail.com>
Newer hardware more strictly enforces buffer lenghts, causing an
mis-set value to be identified. Older hardware won't catch it.
The difference is benign on old hardware.
Set the right embedded buffer length for nvme ios.
