init_etherdev() and friends removed.  They were inherently racy _and_ violated
allocation policy.  Proper replacement is
	dev = alloc_etherdev(size);
	if (!dev)
		FOAD
	set the things up, if failed - free_netdev(dev) and FOAD
	err = register_netdev(dev);
	if (err) {
		clean up after the setup we'd done
		free_netdev(dev);
		FOAD
	}

Note that use of statically allocated net_device is a shootable offense now.
They must be created with alloc_netdev() and its derivatives.

Use of net_device->init() is strongly discouraged.  It has valid uses (most
of them in net/*), but unless all your setup and registration is done under
externally held rtnl, don't do it.  Do your init before register_netdev()
instead.  Blind use of ->init() almost certainly means a leak since we
have no way to tell whether register_netdev() had failed in dev->init() or
after it.

dev_alloc() is removed.  Use alloc_netdev() derivatives instead.  Reason:
use of dev_alloc_name() in it is inherently racy.
