Merge with latest version of the Mylex 6+ driver.
- All sources are built in a single object, reducing namespace pollution. - Kill the ready queue, and handle a busy response to mly_start in callers rather than deferring the command. - Improve our interaction with CAM: - Don't advertise physical channels as SCSI busses by default. - use the SIM queue freeze capability rather than queueing CDBs internally. - force bus reprobe at module load time. - Clean up more resources in mly_free. - Tidy up debugging levels. - Tidy up handling of events (mostly just code cleanliness). - Use explanatory macros for operations on bus/target/channel numbers.

Major update and bugfix for the 'mly' driver.
- Convert to a more efficient queueing implementation. - Don't allocate command buffers on the fly; simply work from a static pool. - Add a control device interface, for later use. - Handle controller overload better as a consequence of the improved queue implementation. - Add support for the XPT_GET_TRAN_SETTINGS ccb, and correctly set the virtual SCSI channels up for multiple outstanding I/Os. - Update copyrights for 2001. - Some whitespace fixes to improve readability.
Due to a misunderstanding on my part, previous versions of the driver were limited to a single outstanding I/O per virtual drive. Needless to say, this update improves performance substantially.
