ipv6: drop packets with multiple fragmentation headers
[ Upstream commit f46078cfcd77fa5165bf849f5e568a7ac5fa569c ]
It is not allowed for an ipv6 packet to contain multiple fragmentation
headers. So discard packets which were already reassembled by
fragmentation logic and send back a parameter problem icmp.
The updates for RFC 6980 will come in later, I have to do a bit more
research here.
