>Description:
	awi driver worked very happy during last IETF meeting period,
	but now it does not work correctly when accessing the card
	with memory mapped i/o.  access via i/o port works fine.

	kernel printf shows the following repeatedly and goes into
	infinite loop:
awi0: no command in progress?
awi0: set_infra failed (card unhappy?); erroffset 0
awi0: reset

	it looks to be some problem in the change into i82365*.c,
	since awi*.c was not changed much since last IETF (Nov 1999).

>How-To-Repeat:
	give enough memory window to pcic0, put awi card and bring it up.
>Fix:
	temporary workaround is to disable memory mapped access mode.
