Well, by "disallowing IPV6=m" I meant "disallowing IPV6=m when
enabling TIPC" for sure... Sorry that it misleads you to believe
completely disallowing IPV6=m globally.

It also disallows TIPC=m and IPV6=m, right? In short, it disalows
IPV6=m when TIPC is enabled. And this is exactly what I complain,
as it looks too harsh.
