See my related comment to the other IPv6 patch in this series.

It is not legal to assume that v4/v6 are an either-or decision,
but it can be either v4-only, v6-only or v4 and v6 in the same PDP context.

For the "peer" (outer) address, I think it is correct to assume only either v4 or v6.

But for the inner "ms" address, it is not.
