ipv6: Add hop-by-hop header to jumbograms in ip6_output
Instead of simply forcing a 0 payload_len in IPv6 header,
implement RFC 2675 and insert a custom extension header.
Note that only TCP stack is currently potentially generating
jumbograms, and that this extension header is purely local,
it wont be sent on a physical link.
This is needed so that packet capture (tcpdump and friends)
can properly dissect these large packets.
