The XBox dongles, while also apparently 8388-based, don't actually work
with the driver or the firmware.  We're not sure if there is additional
hardware in them, or if they have different Boot2 firmware that checks
signatures of the real firmware, or what.  More experimentation and
possibly reverse engineering is necessary to figure out how to upload
firmware to the XBox dongles.

The standard setup (for now) is an XO with a USB Ethernet dongle and the
internal 8388.  Bring up the ethernet device, configure the msh0
interface as AdHoc, give it an SSID, a channel, and an IP address, and
start the 'mpp.py' script.

We'll be plugging 8388 USB dongles into larger servers, but these
dongles are Marvell reference boards and not suitable for production or
long-term use since they are not environmentally sealed, don't have RF
cans, and only have 1 antenna connection point.
