[ofa-general] [PATCH 01/11] IB/ipoib: Export call to call_netdevice_notifiers and add new private flag

[Jay Vosburgh]

From: Moni Shoua <monisonlists at gmail.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.
