The callback function used by zfcp always returns success,
which is an indication for the SCSI midlayer to stop error
handling. Remove the bus_reset callback, since the same
function will be called via the host_reset callback.

Some of our vendors have requested that our adapters ignore the hardware
reset attempts during recovery and have enforced this with changes in
Adapter Firmware. Some of our customers have requested the option to be
able to reset the adapter under adverse adapter failure, we even had a
few defects reported here considering it a regression that the Adapter
could not be reset. This patch addresses this dichotomy. The user can
force the adapter to be reset if it supports the IOP_RESET_ALWAYS
command, in cases where the adapter has been programmed to ignore the
reset, by setting the aacraid.check_reset parameter to a value of -1.

The driver will not reset an Adapter that does not support the reset
command(s).

This patch also fixes and cleans up some of the logic associated with
resetting the adapter.

  - This patch should be commited before:
    usb: transport - convert to accessors and !use_sg code path removal

  - isd200_action() was still using direct liniar pointers in issuing
    commands to the USB transport level. This is no longer supported,
    use one-element scatterlist instead.
  - Adjustment of command's length in the case of scsi-to-ata translation
    is now restored before return to queuecommand, since other wise it can
    leak BIOs.
  - isd200_action() return Error on unknown requests. Used to print an error
    but still try to send garbage cdb.
  - convert few places to scsi data accessors.

I was working on patches which add new transport error values, when I
noticed that DID_REQUEUE was not in the hostbyte_table. I do not think
there is any way to hit the code path where scsi_show_result is called
and where you return DID_REQUEUE, because DID_REQUEUE causes scsi-ml to
always requeue the command. However, for completeness and because I want
to one day send a patch that tries to add new host bytes values, I am
sending this patch.

 1. Create a file "update_bios" in sysfs to allow user to update bios
    from user space.

 2. The BIOS image file can be downloaded from web site

"http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300"
    and copy the BIOS image into /lib/firmware folder.

 3. The aic994xx will accept "update bios_file" and "verify bios_file"
    commands to perform update and verify BIOS image .

    For example:

     Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios"
          to update BIOS image from /lib/firmware/as483c01.ufi file into
          HBA's flash memory.

     Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios"
          to verify BIOS image between /lib/firmware/asc48c01.ufi file
and
          HBA's flash memory.

 4. Type "cat  /sys/devices/.../update_bios" to view the status or
result
    of updating BIOS.
