NAK

It just doesn't.  Take a look at ipw2100_wx_set_scan(); there's no
handling of any SSID stuff in there.  The driver does not support
probe-scans; I'm not sure if the firmware does, but even if it does, the
driver doesn't send the SSID down to the firmware.

Compare this to the ipw2200.c set_scan() function.  It just does not
appear that the ipw2100 supports arbitrary SSIDs for direct scans, which
is why I didn't include this capability when I went around patching the
drivers a few years ago.
