From 37aef4214d211f4c472a1fc7d54eb8b02b443420 Mon Sep 17 00:00:00 2001 From: Helin Zhang Date: Tue, 8 Mar 2016 16:14:13 +0800 Subject: [PATCH] i40e/base: limit version check of DCB XL710/X710 devices requires FW version checks to properly handle DCB configurations from the FW while other devices (e.g. X722) do not, so limit these checks to XL710/X710 only.
