Added module parameter "poll_mode_io" to support for "polling" (reduced interrupt operation). In this mode, IO completion interrupts are delayed. At the end of initiating IOs, the driver schedules for cmd completion if there are pending cmds. A timer-based interrupt has also been added to prevent IO completion from being delayed indefinitely in the case that no new IOs are initiated. Some formatting issues in resume, suspend comment block also corrected Signed-off-by: NBo Yang <bo.yang@lsi.com> Signed-off-by: NJames Bottomley <James.Bottomley@HansenPartnership.com>

1. Setting the max_sectors_per_req based on max SGL supported by the FW. Prior versions calculated this value from controller info's max_sectors_1, max_sectors_2. For certain controllers/FW, this was resulting in a value greater than max SGL supported by the FW. Now we take the min of max sgl from FW and max_sectors calculation. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 10. FW may take a max of 60 seconds to respond to the INIT cmd.

eh_timed_out call back (megasas_reset_timer) is used to throttle io to the adapter when it is called the first time for a scmd. The MEGASAS_FW_BUSY flag is set and can_queue reduced to 16. The can_queue is restored from completion routine in following two conditions : 5 seconds has elapsed and the # of outstanding cmds in FW is < 17.

Sends "Stop Processing" cmd to FW before returning failure from reset routine d. Adds print in megasas_transition routine e. Sends "RESET" flag to FW to do a soft reset of controller to move from Operational to Ready state. f.

The patch adds support for a ZCR controller (Device ID : 0x413). It also has a critical bug fix : Disable controller interrupt before firing INIT cmd to FW. Interrupt is enabled after required initialization is over. This is done to ensure that driver is ready to handle interrupts when it is generated by the controller.

This patch defines a new template to represent each type of controllers (identified by the processor used). The template has members that is set with appropriate values during driver initialisation. This change is done to support new controllers with minimal change to existing code. In future, for a new controller support, a template will be declared and its members initialised appropriately.
