Change 143128 by hselasky at hselasky_laptop001 on 2008/06/08 19:08:52

	
	Final USB WLAN patches after IFC @ 143078 .
	
	URAL, RUM and ZYD USB WLAN adapters have
	been tested and found to work in STA mode
	at least.
	
	Sam: The USB WLAN drivers were
	writing to "ic_myaddr" at "(void *)0", because
	the IC structure is no longer in the softc. So
	you need to store it in the softc and then
	copy it to the IC later. Look at the
	"sc_myaddr" lines in the diff.
