+Release Date : Tues. Dec 14, 2010 17:00:00 PST 2010 -
+ (emaild-id:megaraidlinux@lsi.com)
+ Adam Radford
+Current Version : 00.00.05.29-rc1
+Old Version : 00.00.04.31-rc1
+ 1. Rename megaraid_sas.c to megaraid_sas_base.c.
+ 2. Update GPL headers.
+ 3. Add MSI-X support and 'msix_disable' module parameter.
+ 4. Use lowest memory bar (for SR-IOV VF support).
+ 5. Add struct megasas_instance_temlate changes, and change all code to use
+ new instance entries:
+
+ irqreturn_t (*service_isr )(int irq, void *devp);
+ void (*tasklet)(unsigned long);
+ u32 (*init_adapter)(struct megasas_instance *);
+ u32 (*build_and_issue_cmd) (struct megasas_instance *,
+ struct scsi_cmnd *);
+ void (*issue_dcmd) (struct megasas_instance *instance,
+ struct megasas_cmd *cmd);
+
+ 6. Add code to support MegaRAID 9265/9285 controllers device id (0x5b).
