For performance reasons there is a need to have support for selectable

9-layer and 5-layer topology. This patch series enables switch from
default to 5-layer topology, if user decides to opt-in.

====================
allocate dummy device dynamically
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 helper to allocate a dummy device at dynamically runtime, and
move the Ethernet devices to use it, instead of embedding the dummy
device inside the private structure.
This fixes all the network cases plus some wireless drivers.
PS: Due to lack of hardware, unfortunately most these patches are
compiled tested only, except ath11k that was kindly tested by Kalle Valo.

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:
https://lore.kernel.org/all/20240322082336.49f110cc@kernel.org/
Split the init_dummy_netdev() function in two. Create a new function called
init_dummy_netdev_core() that does not memzero the net_device structure.
Then have init_dummy_netdev() memzero-ing and calling
init_dummy_netdev_core(), keeping the old behaviour.
init_dummy_netdev_core() is the new function that could be called as an
argument for alloc_netdev().
Also, create a helper to allocate and initialize dummy net devices,
leveraging init_dummy_netdev_core() as the setup argument. This function
basically simplify the allocation of dummy devices, by allocating and
initializing it. Freeing the device continue to be done through
free_netdev()

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, will be overwritten and
there will be no way to identify that this is a dummy device. Also, this
device do not need the final put_device(), since dummy devices are not
registered (through register_netdevice()), where the device reference is
increased (at netdev_register_kobject()/device_add()).
