Sorry, module parameters like this are not allowed.

You must use a generic, portable interface, to configure networking
device settings.

Otherwise every other driver that wants to do something similar will
have yet another module option with a different name, and every user
will suffer because they will need to learn a different mechanism
to perform this configuration for every driver.
