Date: Mon, 20 Aug 2007 18:42:19 +0300 From: Moni Shoua <monisonlists@...il.com> To: rdreier@...co.com, davem@...emloft.net, fubar@...ibm.com CC: netdev@...r.kernel.org, general@...ts.openfabrics.org Subject: [PATCH V4 1/10] IB/ipoib: Export call to call_netdevice_notifiers and add new private flag Export the call to raw_notifier_call_chain so modules can send notifications on netdev events to the netdev_chain. Add IFF_SLAVE_DETACH to the list of priv_flags for net_device. This flag is set by a slave that is about to unregisster from the kernel. Both changes are used in bonding slaves that wish to inform the bonding master about coming detachment.
