[PATCH v2] net: tunnels - enable module autoloading

[Tom Gundersen <teg@jklm.no>]

Enable the module alias hookup to allow tunnel modules to be autoloaded on demand.

This is in line with how most other netdev kinds work, and will allow userspace
to create tunnels without having CAP_SYS_MODULE.

v2: add ';'

Hi Dave,

I must have sent out the wrong version of this patch. Sorry for the inconvenience!

Cheers,

Tom
