I admit I foolishly only changed the name to firmware-5.bin to prevent
the minute-long timeout (can we do something about that?), which is
probably the same reason why others were doing it.  But in looking
through the code, I can't find anywhere where the value of ar->fw_api
actually affects driver behaviour.  Could you point me to where this
value becomes important?
