From:   Shannon Nelson <snelson@...sando.io>
To:     snelson@...sando.io, netdev@...r.kernel.org, davem@...emloft.net
Subject: [PATCH v7 net-next 10/19] ionic: Add the basic NDO callbacks for netdev support

Set up the initial NDO structure and callbacks for netdev
to use, and register the netdev.  This will allow us to do
a few basic operations on the device, but no traffic yet.
