See hostap_fw_load in hostap-utils for an example script that loads the
needed firmware files.

More or less, but the exact prism2_srec commands may not have been

Well.. Either one "just knows" the coding mechanism Intersil used for
the file names to indicate which card type they were for or one can try
with prism2_srec whether any given firmware image is suitable (before
asking it to actually download it). In case of D-Link DWL-650 Rev P1 the
files are PM*.HEX as the primary firmware and RF*.HEX as the
secondary/STA firmeare.

There is documentation for this, but not publicly available.. I would
assume that someone has made such a list available somewhere, though.

Well.. This was done before udev, if I remember correctly and anyway,
all that is needed is running "hostap_fw_load wlan0". I believe this was
discussed long time ago on this list (i.e., is archived somewhere) with
examples on how to do this automatically with cardmgr.

I'm not familiar with udev, so I don't know how to do this with more
modern kernels, but if someone is interested in doing that and
documenting the process, I can add the document somewhere..
