[Click] how to test

udpgen.c and udpcount.c are no longer supported because we use straight
Click configurations instead. You can find the udpgen-equivalent in
CLICK/conf/udpgen.click. I've just checked in a udpcount-equivalent, to
CLICK/conf/udpcount.click; it is also attached.

Let us know if you have problems/...

// udpcount.click

// This file is a simple UDP/IP packet counter, meant to be used in the
// Linux kernel module. It counts UDP packets received on port 1234. (Change
// the argument to 'ip_classifier' to use a different port.) See
// 'udpgen.click' for a traffic generator corresponding to udpcount.click.

// The interface's hardware and IP addresses go here.
