I have a really hard time accepting a "fix" that depends upon behavior
that the Linux ipv6 stack doesn't even have.

We actually support this feature:

But it is forbidden when the sysctl I mentioned is set, which is the
default.

I'm talking about default behavior, which is to not reflect.

Oh, yes, understood.

I think we can flip this sysctl by default to off: current default
kernel config actually generates flow labels on its own, so the
description of this sysctl is violated by default anyway, as it doesn't
preserve the uniqueness anymore.

Bye,
