Setting an MTU on a default lxc bridge (lxcbr0)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To modify a container MTU it is also required to set ``lxc_net_mtu`` to
a value other than 1500 in ``user_variables.yml``. It will also be necessary
to modify the ``provider_networks`` subsection to reflect the change.
This will define the mtu on the lxcbr0 interface. An ifup/ifdown will
be required if the interface is already up for the changes to take effect.
