Made kernel accept IPv6 routes with IPv4-mapped address as next-hop.
It is possible to configure IP interfaces with IPv4-mapped addresses, and
one can add IPv6 routes for IPv4-mapped
with an IPv4-mapped address as a nexthop/gateway.
RFC 4798 (a proposed standard RFC) uses IPv4-mapped addresses as nexthops,
thus in order to support that type of address configuration the kernel
needs to allow IPv4-mapped addresses as nexthops.

Thanks - I'll add that.
Also got a warning from the kbuild test robot for route.c which I'll fix.
Thanks!

I am in favor of enabling it by default.
But given that there could be broken implementations out there, we
should give users a choice and provide.
OK, I'

IPv6 duplicate address detection can fail if there is some temporary
