From 5fe118c9fd6b8e129788c88a10ac0af82b255f81 Mon Sep 17 00:00:00 2001 From: Sudarsana Reddy Kalluru Date: Mon, 29 Aug 2016 08:29:52 -0400 Subject: [PATCH] qed*: Disallow dcbx configuration for VF interfaces. Dcbx configuration is not supported for VF interfaces. Hence don't populate the callbacks for VFs and also fail the dcbx-query for VFs.
