115     1. Continue booting immediately if FW in FAULT at driver load time.
210 		which not returned by FW to driver's pending queue.  Driver
211 		will re-issue those pending cmds again to FW after the OCR
218 		d). in Driver's ISR routine, if driver get the FW state as
219 		state change, FW in Failure status and FW support online controller
223 		OCR to finish, then issue the cmds to FW.
226 		OCR to see if driver can bring back the FW.
233 	failed state.  Driver will kill adapter if can't bring back FW after the
253 	PD delete/ADD, LD add/delete from FW.
283 1.	Add the fix of pending in FW after deleted the logic drives.
337 1. Add shutdown DCMD cmd to the shutdown routine to make FW shutdown proper.
354 	particular command is sent to drive, FW is seeing continuous
360 	make sure the FW will 	finish the pending cmd for KDUMP case.
370 1. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 10. FW may take
398 	FW. Prior versions calculated this value from controller info
399 	(max_sectors_1, max_sectors_2). For certain controllers/FW,
401 	by the FW. Issue was first reported by users running LUKS+XFS
405 	10. FW may take a max of 60 seconds to respond to the INIT
466 	3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
493 	Checks added in megasas_queue_command to know if FW is able to

497 	from the time cmds were last sent to FW.
499 ii.	FW enables WCE bit in Mode Sense cmd for drives that are configured
503 	Synhronize cache is not supported by the FW. Driver will short-cycle
504 	the cmd and return success without sending down to FW.
544 ii.	Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same
545 	as Max Cmds FW can support
551 i.	Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
557 v.	If FW in operational state before firing INIT, now we send RESET Flag to FW instead of just READ…
558 vi.	megasas_ctrl_prop structure updated (based on FW struct)
559 vii.	Added print : FW now in Ready State during initialization
565 i.	Added FW transition state for Hotplug scenario
575 ii.	Bug fix : Disable controller interrupt before firing INIT cmd to FW.
