Date: Fri, 14 Sep 2007 16:40:20 -0700 From: Jay Vosburgh <fubar@...ibm.com> To: netdev@...r.kernel.org, rdreier@...co.com, monis@...taire.com Cc: monisonlists@...il.com, ogerlitz@...taire.com, jgarzik@...ox.com, davem@...emloft.net, general@...ts.openfabrics.org, Moni Shoua <monis@...taire.com> Subject: [PATCH 01/11] IB/ipoib: Export call to call_netdevice_notifiers and add new private flag From: Moni Shoua <monisonlists@...il.com> 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.
