Well, need two network ports. Haven't figured out much on interfacing the
thing to offboard gear (I'd have liked it if it had a pci interface). So is
interfacing up a second network card "trivial" on the I/Os provided?

And wanted esata, or some high speed disk I/O interface for captures.

I'd rather like to continue forward on the zedboard front. The prospect of
designing an ethernet chip that actually could incorporate fq_codel etc is
very exciting. The RGII interface is available to access directly, in
particular.
