Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion

Un-embed the net_device from the private struct by converting it
into a pointer. Then use the leverage the new alloc_netdev_dummy()
helper to
There is a new dummy netdev allocator, use it instead of
alloc_netdev()/init_dummy_netdev combination.
Using alloc_netdev() with init_dummy_netdev might cause some memory
corruption at the driver removal side.

It is impossible to use init_dummy_netdev together with alloc_netdev()
as the 'setup' argument.
This is because alloc_netdev() initializes some fields in the net_device
structure, and later init_dummy_netdev() memzero them all. This causes
some problems as reported here:
struct net_device shouldn't be embedded into any structure, instead,
the owner should use the private space to embed their state into
net_device.
But, in some cases the net_device is embedded inside the private
structure, which blocks the usage of zero-length arrays inside
net_device.
Create a

For dummy devices, exit earlier at free_netdev() instead of executing
the whole function. This is necessary, because dummy devices are
special, and shouldn't have the second part of the function executed.
Otherwise reg_state, which is NETREG_DUMMY for dummy devices, will be
overwritten and there
