    sys/dev/hfa          fore_aali.h fore_command.c fore_init.c 
                         fore_intr.c fore_var.h 
  Log:
  Make the driver to work with firmware version 4.1.12 (other 4.X.Y should
  also do it). Three problems have been encountered:
  
  1. The initialisation command does not work in interrupt mode. Whether
     this is a firmware bug or a feature is not clear. The original Fore
     drivers execute the initialize command always in polling mode, so
     it appears that this behaviour is expected. When we detect a 4.X.Y
     firmware do busy wait on the command status.
  
  2. The command code of the GET_PROM command has changed. This is an
     unofficial command anyway. What was GET_PROM in 3.X.Y is CLEAR_STATS
     in 4.X.Y (although unimplemented in the firmware). We need to
     use the correct code depending on the firmware.
  
  3. The 4.X.Y firmware can set the error flag in the command status
     without also setting the completion flag (as the documenation says).
     Check both variants.
  
  An additional field in the per-card structure fu_ft4 is TRUE when we have
  detected a 4.X.Y firmware. Otherwise it is false. The behaviour of the
  driver when using a 3.X.Y firmware should be identical to the previous
  behaviour.
  
  This change will enable traffic shaping of (at least one) CBR channels.
