That means I'll have to maintain this patch outside tree forever? :-)

Really, as I said in IRC I do not compile ipv6 as it does no good for
me anytime soon, once I see the use I can just enable it again. Right
now it just add kernel space, wastes cpu and memory and the worst
thing: pollutes my ifconfig/netstat! ;-) Also gentoo provides a nice
-ipv6 flag to keep it clean, and this patch would fit nice!

For general purpose distros like Fedora it does make sense to support
IPv6, but in my case I run my systems with all required device drivers
built-in and just those that I have... whenever I buy new cards or
change machines I recompile the kernel anyway. So keeping ipv6 for
"one day it may happen" is not something I want.
