  Log:
  If we're using ancient (pre 1.17.0) 2100 f/w (for the cards that cannot
  load f/w images > 0x7fff words), set ISP_FW_ATTR_SCCLUN. We explicitly
  don't believe we can find attributes if f/w is < 1.17.0, so we have to
  set SCCLUN for the 1.15.37 f/w we're using manually- otherwise every
  target will replicate itself across all 16 supported luns for non-SCCLUN
  f/w.
  
  Correctly set things up for 23XX and either fast posting or ZIO. The
  23XX, it turns out, does not support RIO. If you put a non-zero value
  in xfwoptions, this will disable fast posting. If you put ICBXOPT_ZIO
  in xfwoptions, then the 23XX will do interrupt delays but post to the
  response queue- apparently QLogic *now* believes that reading multiple
  handles from registers is less of a win than writing (and delaying)
  multiple 64 byte responses to the response queue.
  
  At the end of taking a a good f/w crash dump, send the ISPASYNC_FW_DUMPED
  event to the outer layers (who can then do things like wake a user
  daemon to *fetch* the crash image, etc.).
