No, I do not expect anything to be perfect.  But I do expect that you,
when adding IPv6 support, don't *knowingly* break existing IPv4
installations.

Well, you have been told that your proposed new feature breaks IPv4
support with specific settings.  I do not think that you are speeding up
anything here by ignoring that fact.  On the contrary.

And net-next was already closed for new features when you sent the last
version, so I really, really do not understand why you are in such a
hurry.  Sorry.

Note that I'm neither an expert or anything else here.  This is just my
personal view. Feel free to ignore it, but please think about it for a
second or two first.
