[Click] Writing your own element

[Amita Ekbote]

Hey,

The element is going to try and measure the link quality. In my element I
have the run_timer which is just sending out packets, I have written a small
client program to make sure that these packets make it. Once a packet is
received the client sends back a packet. I have the pull function which just
contains the pull print statement. I put a print statement before my click
element and it does receive a packet. For processing I have used "a/a" .
