[PATCH 3.11 139/198] net: tunnels - enable module autoloading

[Luis Henriques]

3.11.10.13 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tom Gundersen <teg at jklm.no>

commit f98f89a0104454f35a62d681683c844f6dbf4043 upstream.

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.
