For Broadwell in particular, it is enough to avoid power states lower than C1E, in my experience.

And no, MTU plays no part in the degraded IPv6 performance. I think it's rooted in a less efficient route lookup mechanism (Linux 6.7 was what I tested with), but I did not take the time to check properly.
