[NETFILTER]: nf_nat: pass manip type instead of hook to nf_nat_setup_info
nf_nat_setup_info gets the hook number and translates that to the manip type to perform. This is a relict from the time when one manip per hook could exist, the exact hook number doesn't matter anymore, its converted to the manip type. Most callers already know what kind of NAT they want to perform, so pass the maniptype in directly. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
