Subject: IPv6 defrag question ?

Hi 
While testing HMARK and IPv6 with nf_defrag_ipv6 (and nf_conntrack_ipv6 loaded) I can't see the defrag ?

>From what I can see nf_conntrack_reasm goes into PREROUTING with prio -400
and HMARK in PREROUTING with prio -150

I was expecting that the reasaembled packet whould reach HMARK not the fragments.

(Debug print from hmark)
HMARK() mark:489, hash:4d04eaa1, frag:1, nhoffs:30 plen:1408 (2008::10 - 1000::1)
HMARK() mark:489, hash:4d04eaa1, frag:1, nhoffs:0  plen:86 (2008::10 - 1000::1)

IPv4 do reassm. the packets not IPv6...
