Define the 32 Bit Mode Command Control Block (CCB) structure. The first 40

- Unit field in byte 17 expanded to 6 bits; unfortunately, using a union of
- structs containing enumeration type bitfields to provide both definitions
- leads to packing problems, so the following definition is used which requires
- setting TagEnable to Logical Unit bit 5 in 64 LUN Format CCBs.
+ bytes are defined by and common to both the MultiMaster Firmware and the

+ byte 1, and the Logical Unit field in byte 17 expanded to 6 bits. In theory,
+ Extended LUN Format CCBs can support up to 64 Logical Units, but in practice
+ many devices will respond improperly to Logical Units between 32 and 63, and
+ the SCSI-2 specification defines Bit 5 as LUNTAR. Extended LUN Format CCBs
+ are used by recent versions of the MultiMaster Firmware, as well as by the
+ FlashPoint SCCB Manager; the FlashPoint SCCB Manager only supports 32 Logical
+ Units. Since 64 Logical Units are unlikely to be needed in practice, and
+ since they are problematic for the above reasons, and since limiting them to
+ 5 bits simplifies the CCB structure definition, this driver only supports
+ 32 Logical Units per Target Device.
