Using nfct_extend alleviates that problem and hopefully paves way
for inclusion of the module.
Sorry, I would not reserve an entry unless I know what xt_portscan is.

Just send the patch please.


I feel the same way. And I would like to know why it needs
connection state. That seems counterintuitive to a portscan
detector, which is by definition trying to detect something
happening in multiple connections.

Is it so? Maybe it should be called portscantype then, but what's in a name.
