Hi,
I found a small problem with if_wi.c in FreeBSD(3.3-RELEASE and later,
probably 4.1.1 too)
After using WaveLan PCMCIA card,
other PCMCIA cards do not work properly.
(they work for a while but become inoperable sometime.)
This problem is due to the timeout route in if_wi.c,
wi_inquire(). I'm afraid that untimeout() should
be call for it when a WaveLan PCMCIA card is just unloaded,
like following context diff (based on FreeBSD 3.3-RELEASE).
