Oh, no. This is not the way. It needs to be a runtime configuration
option (a netlink attribute). Generally, every time you find yourself
adding a module parameter, you're doing something wrong.

Also, net-next is currently closed. You should not submit new features
during this period, it's bugfixes only now.
