Below is the change set in MPI2 Rev Y specification and in 2.00.17 header files
1) Added SCSIStatusQualifier to SCSI IO Error Reply message.
2) Added ATA Security Freeze Lock to IO Unit Page 1 Flags field.

Below is the change set in MPI2 Rev Z specification and in 2.00.19 header files
1) Added reserved fields to IO Unit Page 7 for future use.
2) Added optional functionality to IOCInit Request so that
   the host may specify a separate base address for each
   Reply Descriptor Post Queue. IOC support for this is
   indicated using a new IOCCapabilities bit in the IOCFacts Reply.
3) Added Toolbox Console Text Display Tool
   The host uses the Console Text Display Tool to send a string to
   IOC's Console using different console types (eg: UART serial terminal or Ethernet terminal).

Added driver module parameter max_msix_vectors. Using this
module parameter the maximum number of MSI-X vectors could be set.

The number of MSI-X vectors used would be the minimum of MSI-X vectors
supported by the HBA, the number of CPU cores and the value set to
max_msix_vectors module parameters.

The PCI register read checking introduced in commit fe1b806f
("qla2xxx: Disable adapter when we encounter a PCI disconnect") is
active during driver probe. Hold off scheduling any board removal until
the driver probe has completed. This ensures that the the board_disable
work structure is initialized and more importantly, avoids racing
qla2x00_probe_one.

Introduce mutual exclusion between the qla2xxx_remove_one PCI driver
callback and qla2x00_disable_board_on_pci_error, which is scheduled as
board_disable work by qla2x00_check_reg{32,16}_for_disconnect:

* Leave the driver-specific data attached to the underlying PCI device
intact in qla2x00_disable_board_on_pci_error, so that qla2x00_remove_one
has enough breadcrumbs to determine that any board_disable work has been
completed.

* In qla2xxx_remove_one, set a bit to prevent any subsequent
board_disable work from scheduling, then cancel and wait until pending
work has completed.

* Reuse the PCI device enable count check in qla2x00_remove_one to
determine if board_disable has occured. The original purpose of this
check was unnecessary since the driver remove function wasn't called
when the probe fails.
