50 1.2.2.2 sommerfe * The 79c930 contains a bus interface unit, a media access
51 1.2.2.2 sommerfe * controller, and a tranceiver attachment interface.
52 1.2.2.2 sommerfe * The MAC contains an 80188 CPU core.
53 1.2.2.2 sommerfe * typical devices built around this chip typically add 32k or 64k of
54 1.2.2.2 sommerfe * memory for buffers.
55 1.2.2.2 sommerfe *
56 1.2.2.2 sommerfe * The 80188 runs firmware which handles most of the 802.11 gorp, and
57 1.2.2.2 sommerfe * communicates with the host using shared data structures in this
58 1.2.2.2 sommerfe * memory; the specifics of the shared memory layout are not covered
59 1.2.2.2 sommerfe * in this source file; see <dev/ic/am80211fw.h> for details of that layer.
