e6c12d85d0 Major update to the 'twe' driver.
- Layout reorganisation to enhance portability.  The driver now has
   a relatively MI 'core' and a FreeBSD-specific layer over the top.
   Since the NetBSD people have already done their own port, this is
   largely just to help me with the BSD/OS port.

 - Request ID allocation changed to improve performance (I'd been
   considering switching to this approach after having failed to come
   up with a better way to dynamically allocate request IDs, and seeing
   Andy Doran use it in the NetBSD port of the driver convinced me
   that I was wasting my time doing it any other way).  Now we just
   allocate all the requests up front.

 - Maximum request count bumped back to 255 after characterisation
   of a firmware issue (off-by-one causing it to crash with 256
   outstanding commands).

 - Control interface implemented.  This allows 3ware's '3dm' utility to
   talk to the controller.  3dm will be available from 3ware shortly.

 - Controller soft-reset feature added; if the controller signals a
   firmware or protocol error, the controller will be reset and all
   outstanding commands will be retried.

b1e68a44b5 Reduce the number of outstanding commands we will send to the controller
to 50.  This has been reported to avoid the problems that many users have
been experiencing with crashing the card firmware during rebuilds.

4b85df4ea6 Remove some confusing verbosity - we have no idea what RAID level the
drive is at, so don't print the 'unknown' value, just say nothing.
