From a8eaed55f86ec45a58414ffd04818be641b9e0de Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Thu, 1 Aug 2013 11:36:42 -0400 Subject: [PATCH] tile: set hw_features and vlan_features in setup This change allows the user to configure various features of the tile networking drivers on and off. There is no change to the default initialization state of either the tilegx or tilepro drivers. Neither driver needs the ndo_fix_features or ndo_set_features callbacks, since the generic code already handles the dependencies for fix_features, and there is no hardware state to tweak in set_features.
