This patch changes flow hashing to use jhash2 over the flow_keys

This patch adds full IPv6 addresses into flow_keys and uses them as
input to the flow hash function. The implementation supports either
IPv4 or IPv6 addresses in a union, and selector is used to determine
how may words to input to jhash2.

We don't need to return the IPv6 address hash as part of flow keys.

Send icmp pmtu error if we find that the largest fragment of df-skb
exceeded the output path mtu.
The ip output path will still catch this later on but we can avoid the
forward/postrouting hook traversal by rejecting right away.
This is what ipv6 already does.
