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:
		selection of infrastructure/adhoc mode
		ESSID
		...
