Thanks for the link Robert,

This looks like another great option if 10/100 is sufficient for
debugging purposes.

These devices, coupled with WireShark or tcpdump make a great debugging
tool.

Say, if anyone is interested in writing a nice appnote

   ( http://etherboot.org/wiki/appnotes )	

with screenshots and examples of how to use a port-mirroring switch to
do a packet capture with WireShark and tcpdump for debugging gPXE, I
would be happy to donate such a switch as thanks. :)

What I have in mind is an article we can point people to to help get
them up to speed with debugging networking problems.

Please contact me off-list if you are interested.
