Subject: [PATCH v3 1/4] mpt3sas: Added print to notify cable running at a degraded speed.
Date: Mon, 23 Jan 2017 15:26:07 +0530 [thread overview]
Message-ID: <1485165370-43401-2-git-send-email-chaitra.basappa@broadcom.com> (raw)
In-Reply-To: <1485165370-43401-1-git-send-email-chaitra.basappa@broadcom.com>
Driver processes the event MPI26_EVENT_ACTIVE_CABLE_DEGRADED
when a cable is present and is running at a degraded speed
(below the SAS3 12 Gb/s rate). Prints added
to inform the user that the cable is not running at
optimal speed.
