+i. PCI_DEVICE macro used
+
+ Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.
+
+ - Henrik Kretzschmar <henne@...htwindheim.de>
+ii. All compiler warnings removed
+iii. megasas_ctrl_info struct reverted to 3.02 release
+iv. Default value of megasas_dbg_lvl set to 0
+v. Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
+vi. In megasas_teardown_frame_pool(), cmd->frame was passed instead of
+ cmd->sense to pci_pool_free. Fixed. Bug was pointed out by
+ Eric Sesterhenn

+i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
+ New varible added to set dbg level.
+ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078
+iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
+ 3 SGE for 32 bit SGL
+iv. Tasklet added for cmd completion
+v. If FW in operational state before firing INIT, now we send RESET Flag to FW instead of just READY. This is used to do soft reset.
+vi. megasas_ctrl_prop structure updated (based on FW struct)
+vii. Added print : FW now in Ready State during initialization
