ipvs: Complete IPv6 fragment handling for IPVS
IPVS now supports fragmented packets, with support from nf_conntrack_reasm.c
Based on patch from: Hans Schillstrom.
IPVS do like conntrack i.e. use the skb->nfct_reasm
(i.e. when all fragments is collected, nf_ct_frag6_output()
starts a "re-play" of all fragments into the interrupted
PREROUTING chain at prio -399 (NF_IP6_PRI_CONNTRACK_DEFRAG+1)
with nfct_reasm pointing to the assembled packet.)
Notice, module nf_defrag_ipv6 must be loaded for this to work.
Report unhandled fragments, and recommend user to load nf_defrag_ipv6.
To handle fw-mark for fragments. Add a new IPVS hook into prerouting
chain at prio -99 (NF_IP6_PRI_NAT_DST+1) to catch fragments, and copy
fw-mark info from the first packet with an upper layer header.
IPv6 fragment handling should be the last thing on the IPVS IPv6
missing support list.
