Polling Linux

So apparently ToDevice figures out if the device is polling-capable, and
acts appropriately?

I tried the Idle -> ToDevice() setup and I did get packets in and out of
the box. I haven't verified that the polling works yet because the
machine I have here doesn't polling-supported Ethernet card. That'll
have to wait until Monday.

I also tried this setup, just for fun:

cl::Classifier(12/0806, 12/0800);

FromLinux(fake0, 192.168.1.101/24) ->  cl;
cl[0] -> ARPResponder(0.0.0.0/0 1:1:1:1:1:1) -> ToLinux;
cl[1] -> Queue -> ToDevice(eth0);


(And I changed the kernel routing table to send stuff out fake0).

That didn't work at all--I can see stuff going out fake0, but nothing
goes out eth0. The ARPResponder is working (as I can see from looking at
the arp table). Should this work? What have I done wrong?

Sorry if these questions are newbie, but I've just started looking at
this code and I'm trying to get my feet on the ground.
