    sys/dev/hfa          fore_aali.h fore_command.c fore_init.c

  Log:
  MFC fore_aali.h:1.4, fore_command.c:1.15, fore_init.c:1.14,
  fore_intr.c:1.10, fore_var.h:1.8: 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 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 can set the error flag in command status without also setting
     the completion flag (as the documentation 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 3.X.Y should be identical to the previous behaviour .
  
  This change will enable traffic shaping of CBR channels.
