Warner Losh 0d5c223da4 Awi driver, ported from NetBSD from Atsushi Once-san.
From the README:
	Any IEEE 802.11 cards use AMD Am79C930 and Harris (Intersil) Chipset
	with PCnetMobile firmware by AMD.
	   BayStack 650   1Mbps Frequency Hopping PCCARD adapter
	   BayStack 660   2Mbps Direct Sequence PCCARD adapter
	   Icom SL-200    2Mbps Direct Sequence PCCARD adapter
	   Melco WLI-PCM  2Mbps Direct Sequence PCCARD adapter
	   NEL SSMagic    2Mbps Direct Sequence PCCARD adapter
	   Netwave AirSurfer Plus
			  1Mbps Frequency Hopping PCCARD adapter
	   Netwave AirSurfer Pro
			  2Mbps Direct Sequence PCCARD adapter

Known Problems:
	WEP is not supported.
	Does not create IBSS itself.
	Cannot configure the following on FreeBSD:

* The 79c930 contains a bus interface unit, a media access
* controller, and a tranceiver attachment interface.
* 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.
