ipv6: reassembly: use seperate reassembly queues for conntrack and local delivery
Currently the same reassembly queue might be used for packets reassembled
by conntrack in different positions in the stack (PREROUTING/LOCAL_OUT),
as well as local delivery. This can cause "packet jumps" when the fragment
completing a reassembled packet is queued from a different position in the
stack than the previous ones.
Add a "user" identifier to the reassembly queue key to seperate the queues
of each caller, similar to what we do for IPv4.
