  Log:
  After extensive QA cycles at 3ware, bring the driver in-line with all the
  issues which they found and asked to be changed so 3ware can offcially
  support the driver.
  
  Summary of the most significant changes:
  
  - TWE_OVERRIDE is no longer supported
  - If twe_getparam failed, bogus data would be returned to the caller
  - Cache the device unit in the twe_drive structure to aid debugging
  - Add the 3ware driver version.
  - Proper return error codes for many functions.
  - Track the minimum queue length statistics
  - 4.x compat: use the cached unit number from the twe_drive structure
    instead of the the cached si_drv2.  3ware found that after many loads
    and unloads that si_drv2 became corrupted.  This did not happen in
    -current.
