Which can make it interesting since we can query itself over the
network via a router to itself:

Note that we have a hacked up/down. You might try to "ifconfig down" the
interface and see if that breaks things and it "up" brings it back to
life. With the Broadcom NIC we have to be careful to keep the
window short when the NIC's IPMI/ASF stack is not up.
