Subject: [ofa-general] [PATCH V4 1/10] IB/ipoib: Export call to call_netdevice_notifiers and add new private flag
Date: Mon, 20 Aug 2007 18:42:19 +0300	[thread overview]
Message-ID: <46C9B65B.5000500@gmail.com> (raw)
In-Reply-To: <46C9B474.5020202@voltaire.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.
