please give me some comment about use of 
	pcmcia_function_{enable,disable} in wi driver.

	wi_attach() used to finish without pcmcia_function_disable().
	I noticed this and added a call to pcmcia_function_disable() at the
	last stage in wi_attach, to avoid duplicated call to
	pcmcia_function_enable using same sc->sc_pf.
http://cvsweb.netbsd.org/bsdweb.cgi/syssrc/sys/dev/pcmcia/if_wi.c.diff?r1=1.4&r2=1.5

	the old behavior allowed us to perform wiconfig before IFF_UP.
	now it is not possible.

	I would like to hear your words about which is the desired behavior,
	and what is the right fix here.
