75e4d88db4 Fix for a problem seen only on 6xxx series controllers, where-in the
driver tries to submit the same request repeatedly, on finding the
controller cmd queue to be full.

c2d083bbba 1. Better handle a return value of EINPROGRESS from bus_dmamap_load.
2. Check for bad return value from twe_map_request in places where there
   was no checking.

c9c7976f7f Device megapatch 1/6:
Free approx 86 major numbers with a mostly automatically generated patch.

A number of strategic drivers have been left behind by caution, and a few
because they still (ab)use their major number.

a85e26c4bf 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.

235a79707a Properly support the 3ware generic API.
- Build SGL's for ATA_PASSTHROUGH commands
- Fallback to using the sgl_offset when the opcode is unknown for building
  SGL's/
- Add ioctl calls for adding and removing units.
- Define previously undefined AEN's
- Allocate memory for the ioctl payload in multiples of 512bytes.

282070b3e8 Minor updates:
- Rework of twe_report_request to use the command status value rather
   than the flags register. (Joel Jacobson @ 3ware)
 - Update to match some changes in -current vs. stable.

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.
