     *   Atheros chipsets are identified by code in the VS_SW_VER vendor
     *   specific management message; the chipset [] vector translates a
     *   chipset code to a chipset name;
     *
     *   the basic assumption is that the firmware always tells the truth
     *   but the bootrom does not; because of engineering changes, the
     *   firmware uses a different device identification scheme than that
     *   used by the bootrom and that information appears in different
     *   locations depending on the source of the VS_SW_VER confirmation;
     *   see the Programmer's Guide for more information.
