Bela Ban resolved JGRP-1662.
----------------------------

    Resolution: Won't Fix


Leaving MFC and FRAG2 in actually led to better performance than removing them. So I won't do this.

> When run with a TCP transport, we don't need MFC and FRAG(2). However, if we remove FRAG2, the bundler at the transport will drop a message if it exceeds max_bundle_size.
> Let's therefore bypass message bundling when the transport is TCP (TCP has its own batching).
> TODO: measure how this change affects performance on a 4 node cluster. If positive, commit it.
