From 1726442e115a9e58f40747d009a5b4f303e0840a Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Mon, 23 Aug 2010 16:26:41 +0000 Subject: net: increase the size of priv_flags and add IFF_OVS_DATAPATH IFF_OVS_DATAPATH is a place-holder for the Open vSwitch datapath which I am preparing to submit for merging. As all 16 bits of priv_flags are already assigned flags, also increase the size of priv_flags to 32 bits. Unfortunately, by my calculations this increases the size of struct net_device by 4 bytes on 32bit architectures and 8 bytes on 64 bit architectures. I couldn't see an obvious way to avoid that.
