Please minimize the crazy pointer casting in this series.
All of these casts between ipv4/ipv6 route objects and dsts are
completely unnecessary.
Prefer to maintain an rt/rt6 in local variables, and then when you
need the dst say >dst, or to get the device say rt6->dst.dev or
similar.
Thanks.
Initial support for VRF in IPv6 stack. Makes IPv6 functionality
on par with IPv4 -- ping, tcp client/server and udp client/server
all work fine. tcpdump on vrf device and external tap (e.g., host
side tap device) shows all packets with proper addresses. IPv6
does not need the source address
