Re: Kernel and Intel Driver Versions and Click Patches

The PollDevice might help you to *evade* your problem.
But it looks like click has a bug which we have to fix.

Generally speaking.
PollDevice performs much better performance than FromDevice.
And it uses other mechanism compare to FromDevice.
In your case, as Roman pointed out, if you try to put PollDevice, even
if it does nothing except drops packets will change your router's
behavior.

BTW, I'm Joonwoo :-)
