+
+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@nachtwindheim.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.     Added Reboot notify
+ii.    Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same
+       as Max Cmds FW can support

+
+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
