The positive effect of a macro is that if would allow MadWifi to prepare
in advance by testing if GET_NETDEV_DEV is defined.

The functions may or may not be useful for the code in the kernel, but
I'll not be able to prepare MadWifi unless I know the kernel version in
which they will appear.

Considering the drivers that are already in the kernel, you may prefer
to have a more high-level function that would clone the network device
by copying most of the net_device structure.  I think netdev_get_pdev()
would be mostly used for such cloning if implemented.
