ipv6: Add GSO support on forwarding path
commit 0aa68271510ae2b221d4b60892103837be63afe4 upstream.
Currently we disallow GSO packets on the IPv6 forward path.
This patch fixes this.
Note that I discovered that our existing GSO MTU checks (e.g.,
IPv4 forwarding) are buggy in that they skip the check altogether,
when they really should be checking gso_size + header instead.
I have also been lazy here in that I haven't bothered to segment
the GSO packet by hand before generating an ICMP message. Someone
should add that to be 100% correct.
