The match seems to make the most sense where an input device
is available, so

	.hooks = (1 << NF_INET_PRE_ROUTING) | (1 << NF_INET_LOCAL_IN) |
	         (1 << NF_INET_FORWARD)

should probably be added.

Then routing wouldn't work...

I suppose it could be useful to to different chains for routed vs non-routed
packets on pre-routing chain, but on forward chain it wouldn't really
do anything useful.
