Log:
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.
