From 04ed3e741d0f133e02bed7fa5c98edba128f90e7 Mon Sep 17 00:00:00 2001 From: Michał Mirosław Date: Mon, 24 Jan 2011 15:32:47 -0800 Subject: net: change netdev->features to u32 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Quoting Ben Hutchings: we presumably won't be defining features that can only be enabled on 64-bit architectures.
