OpenVPN has several command line option to configure how to handle the
MTU of packets. The plugin accepts a OpenVPN.MTU options which is
translated to '--mtu'. This options not available (has it ever
existed?) since 2.0. We recommend at least version 2.2 of OpenVPN.

It looks like no one is using this, because if he did, OpenVPN bails
out and complains about unknown --mtu option.

In this light, let's drop it and add the exising MTU releated options.

Hi,

I couldn't get my VPN working due to MTU missmatch.

cheers,
daniel
