Update the installation instructions for the switches. I think I have
everything figured out for setting up the private vlan on both switches. There is a wire from eth1 on the control node to a port on the control switch. Another wire from eth2 to a port on the experimental switch. The complication on the control switch is that we have no serial console, and so we actually have another wire from eth3 to the control switch, so that we can dhcp and then log in and do a switcherroo to get the private vlan configured.
