Keep in mind that doing huge patches that modify upstream source should
be submitted for upstream inclusion, otherwise when there is a new
version for inclusion it might break everything up again.
With regards to IPv6 support i think (and it's a completely personal
opinion) that it's no big deal with the iproute2 case, adding IPv6
support won't make things much bigger than say using real iproute2
versus small busybox iproute2-compatible utils.
Granted, you loose some functionality, but if you want the advanced
stuff you might as well throw IPv6 in.
