* The 79c930 contains a bus interface unit, a media access

* The MAC contains an 80188 CPU core.
* typical devices built around this chip typically add 32k or 64k of
* memory for buffers.
*
* The 80188 runs firmware which handles most of the 802.11 gorp, and
* communicates with the host using shared data structures in this
* memory; the specifics of the shared memory layout are not covered
* in this source file; see <dev/ic/am80211fw.h> for details of that layer.
