The following is a random collection of documentation regarding

-==================================
+struct net_device lifetime rules
+================================
Network device structures need to persist even after module is unloaded and
must be allocated with alloc_netdev_mqs() and friends.
If device has registered successfully, it will be freed on last use
-by free_netdev(). This is required to handle the pathologic case cleanly
-(example: rmmod mydriver </sys/class/net/myeth/mtu )
+by free_netdev(). This is required to handle the pathological case cleanly
+(example: ``rmmod mydriver </sys/class/net/myeth/mtu``)
-alloc_netdev_mqs()/alloc_netdev() reserve extra space for driver
+alloc_netdev_mqs() / alloc_netdev() reserve extra space for driver
private data which gets freed when the network device is freed. If
separately allocated data is attached to the network device
-(netdev_priv(dev)) then it is up to the module exit handler to free that.
+(netdev_priv()) then it is up to the module exit handler to free that.
+
+There are two groups of APIs for registering struct net_device.
+First group can be used in normal contexts where ``rtnl_lock`` is not already
+held: register_netdev(), unregister_netdev().
+Second group can be used when ``rtnl_lock`` is already held:
+register_netdevice(), unregister_netdevice(), free_netdevice().
+
+Simple drivers
+--------------
+
+Most drivers (especially device drivers) handle lifetime of struct net_device
+in context where ``rtnl_lock`` is not held (e.g. driver probe and remove paths).
+
+In that case the struct net_device registration is done using
+the register_netdev(), and unregister_netdev() functions:
+
+.. code-block:: c
+
+ int probe()
+ {
+ struct my_device_priv *priv;
+ int err;
+
+ dev = alloc_netdev_mqs(...);
+ if (!dev)
+ return -ENOMEM;
+ priv = netdev_priv(dev);
+
+ /* ... do all device setup before calling register_netdev() ...
+ */
+
+ err = register_netdev(dev);
+ if (err)
+ goto err_undo;
+
+ /* net_device is visible to the user! */
+
+ err_undo:
+ /* ... undo the device setup ... */
+ free_netdev(dev);
+ return err;
+ }
+
+ void remove()
+ {
+ unregister_netdev(dev);
+ free_netdev(dev);
+ }
+
+Note that after calling register_netdev() the device is visible in the system.
+Users can open it and start sending / receiving traffic immediately,
+or run any other callback, so all initialization must be done prior to
+registration.
+
+unregister_netdev() closes the device and waits for all users to be done
+with it. The memory of struct net_device itself may still be referenced
+by sysfs but all operations on that device will fail.
+
+free_netdev() can be called after unregister_netdev() returns on when
+register_netdev() failed.
+
+Device management under RTNL
+----------------------------
+
+Registering struct net_device while in context which already holds
+the ``rtnl_lock`` requires extra care. In those scenarios most drivers
+will want to make use of struct net_device's ``needs_free_netdev``
+and ``priv_destructor`` members for freeing of state.
+
+Example flow of netdev handling under ``rtnl_lock``:
+
+.. code-block:: c
+
+ static void my_setup(struct net_device *dev)
+ {
+ dev->needs_free_netdev = true;
+ }
+
+ static void my_destructor(struct net_device *dev)
+ {
+ some_obj_destroy(priv->obj);
+ some_uninit(priv);
+ }
+
+ int create_link()
+ {
+ struct my_device_priv *priv;
+ int err;
+
+ ASSERT_RTNL();
+
+ dev = alloc_netdev(sizeof(*priv), "net%d", NET_NAME_UNKNOWN, my_setup);
+ if (!dev)
+ return -ENOMEM;
+ priv = netdev_priv(dev);
+
+ /* Implicit constructor */
+ err = some_init(priv);
+ if (err)
+ goto err_free_dev;
+
+ priv->obj = some_obj_create();
+ if (!priv->obj) {
+ err = -ENOMEM;
+ goto err_some_uninit;
+ }
+ /* End of constructor, set the destructor: */
+ dev->priv_destructor = my_destructor;
+
+ err = register_netdevice(dev);
+ if (err)
+ /* register_netdevice() calls destructor on failure */
+ goto err_free_dev;
+
+ /* If anything fails now unregister_netdevice() (or unregister_netdev())
+ * will take care of calling my_destructor and free_netdev().
+ */
+
+ return 0;
+
+ err_some_uninit:
+ some_uninit(priv);
+ err_free_dev:
+ free_netdev(dev);
+ return err;
+ }
+
+If struct net_device.priv_destructor is set it will be called by the core
+some time after unregister_netdevice(), it will also be called if
+register_netdevice() fails. The callback may be invoked with or without
+``rtnl_lock`` held.
+
+There is no explicit constructor callback, driver "constructs" the private
+netdev state after allocating it and before registration.
+
+Setting struct net_device.needs_free_netdev makes core call free_netdevice()
+automatically after unregister_netdevice() when all references to the device
+are gone. It only takes effect after a successful call to register_netdevice()
+so if register_netdevice() fails driver is responsible for calling
+free_netdev().
+
+free_netdev() is safe to call on error paths right after unregister_netdevice()
+or when register_netdevice() fails. Parts of netdev (de)registration process
+happen after ``rtnl_lock`` is released, therefore in those cases free_netdev()
+will defer some of the processing until ``rtnl_lock`` is released.
+
+Devices spawned from struct rtnl_link_ops should never free the
+struct net_device directly.
+
+.ndo_init and .ndo_uninit
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``.ndo_init`` and ``.ndo_uninit`` callbacks are called during net_device
+registration and de-registration, under ``rtnl_lock``. Drivers can use
+those e.g. when parts of their init process need to run under ``rtnl_lock``.
+
+``.ndo_init`` runs before device is visible in the system, ``.ndo_uninit``
+runs during de-registering after device is closed but other subsystems
+may still have outstanding references to the netdevice.
