TODOs for nf_conntrack (last changed Feb 15 2005)
-------------------------------------------------

Some items are controversial, so make sure to get some feedback on
netfilter-develbefore working on any of these.

- Function/structure name unification: s/nf_conntrack/nf_ct/
- Replace get_features stuff by ct_extend ?
- Don't waste space for IPv4 tuples (currently union with IPv6 tuples) ?
- kill ->confirm, nf_conntrack_confirm is generic
- Add nf_ct_get_afinfo for things like ip_ct_attach
- Some IPv4/IPv6 registered hook functions just call generic functions, this
  means even longer call-chains. Add family argument to hook functions and
  kill them ?
- IPv4 NAT
