Message-Id: <1299320969-7951-6-git-send-email-jpirko@redhat.com>

Subject: [patch net-next-2.6 5/8] bonding: get rid of IFF_SLAVE_INACTIVE netdev->priv_flag
Since bond-related code was moved from net/core/dev.c into bonding,
IFF_SLAVE_INACTIVE is no longer needed. Replace is with flag "inactive"
stored in slave structure
