That comment should be considered obsolete. The current code works hard
to ensure that we replay using the same connection (or at least the
same source/dest IP+ports) so that NFSv3/v4.0 DRCs work as expected.
For that reason we've had NFSv3 support since the feature was merged.
The NFSv4.0 support was just forgotten.
