From 147a90887baa98d73db1fa7ed9e755bf48960c21 Mon Sep 17 00:00:00 2001 From: Shahed Shaikh <shahed.shaikh@qlogic.com> Date: Tue, 21 May 2013 09:27:01 +0000 Subject: qlcnic: Fix updating netdev->features o After change in EPORT features of 82xx adapter, netdev->features needs to be updated to reflect EPORT feature updates but driver was manipulating netdev->features at wrong place. o This patch uses netdev_update_features() and .ndo_fix_features() to update netdev->features properly.
