Subject: [patch net-next-2.6 3/6] net: get rid of multiple bond-related netdevice->priv_flags
Date: Sat, 12 Mar 2011 14:14:36 +0100 [thread overview]
Message-ID: <1299935679-18135-4-git-send-email-jpirko@redhat.com> (raw)
In-Reply-To: <1299935679-18135-1-git-send-email-jpirko@redhat.com>
Now when bond-related code is moved from net/core/dev.c into bonding
code, multiple priv_flags are not needed anymore. So toss them out.
