hi ,
  when I study the source , I find that in function nf_hook_slow (linux-2.4.7-10/net/core/netfilter.c ) , there is no sentence  for NF_STOLEN.I want to know how to deal with this case.
  By the way , it seems that CONFIG_NETFILTER_DEBUG has never been defined . so in function nf_iterate (linux-2.4.7-10/net/core/netfilter.c ) , we will never execute
case NF_ACCEPT , and so on . Is it the case? Thanks.
