1.3 Bug Fixes

Between versions 2.1.1.0 and 2.1.2.0:

 * Improvement: Add support to unload driver with QLFXXX.

 * Problem Description: Vmkmgmt-keyval instance does not display all
NPIV port's information.
 * Solution: Create multiple key value management instances per vmhba.

 * Problem Description: When new opcode added to existing template,
we often see data size mismatch between collected data and total
minidump data size.
 * Solution: Skip the entry and adjust the total buffer size by
subtracting the size of skipped opcode from total minidump size.

 * Improvement: Remove unnecessary delays from fw dump code path and add
features to track the failure at various different stages during capturing
the firmware dump.

 * Improvement: Adding support for FA-WWPN functionality.

 * Improvement: Updated Release Notes recommended by Marketing Team.

 * Problem Description: Setting extended error logging causes the system
to PSOD.
 * Solution: PSOD was caused because of dereferencing a invalid pointer.
Added check before dereferencing pointer.

 * Improvement: Add D-Port functionality.

 * Problem Description: PSOD seen in case of 8G ISP reset recovery path.
 * Solution: In case of FCET enable mbx failure, we try to free the fcet
dma buffer using unassigned dma address. We need to use the global
ha->fcet_dma address instead.

 * Problem Description: PSOD seen while running CT_Ping from application.
 * Solution: Allocation DMA memory for msiocb_passthru ioctl command wih
maximum size between reqest_length and response_length.

 * Problem Description: Driver frees the cmd and returns error in case of
timeout and when we receive response after 66 sec we hit an invalid condition.
 * Solution: Increase driver timeout to (66 * 5) sec.

 * Improvement: Adding Application level support for D-port feature.

 * Improvement: Improvement in FDMI attributes

 * Improvement: Allow nvram bit to enable/disable FA-WWPN

 * Improvement: In case of FAWWPN, revert back to the factory wwpn
when the driver marks the LOOP as DEAD.
