Gigabit Ethernet Packet Shaper

[CHANGE username to just westes]

I am looking for a software based packet shaper for testing gigabit
ethernet networks. It needs to have very flexible configuration parameters
for shaping traffic, and ideally should have an API so this can all be
controlled in real-time through software.

Ideally it needs to run at wire speed. Maybe someone has modified
a free Linux kernel to support traffic shaping functions for the IP layer?

There are plenty of traffic shaping functions you can perform with
modern Linux kernel. Here are some links:
