Subject: [net-next 02/21] ixgbe: Report driver version to firmware for x550 devices
Date: Fri, 30 Dec 2016 01:33:22 -0800 [thread overview]
Message-ID: <20161230093341.14674-3-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20161230093341.14674-1-jeffrey.t.kirsher@intel.com>
From: Tony Nguyen <anthony.l.nguyen@intel.com>
Some x550 devices require the driver version reported to its firmware; this
patch sends the driver version string to the firmware through the host
interface command for x550 devices.
