Yi Zou 05cc739073 [SCSI] fcoe: Add sysfs parameter to fcoe for minimum DDP read I/O size ... This adds fcoe_ddp_min as a module parameter for fcoe module to: /sys/module/fcoe/parameters/ddp_min It is observed that for some hardware, particularly Intel 82599, there is too much overhead in setting up context for direct data placement (DDP) read when the requested read I/O size is small. This is added as a module parameter for performance tuning and is set as 0 by default and user can change this based on their own hardware.
