From: Vasu Dev <[email protected]> The current cmd_per_lun value is 32 while other FC HBAs such as lpfc and qlax are using 3, so reduced this to 3 in fcoe also.
I noticed thrash in using 32 cmd_per_lun in stressing 256 luns causing lots of retries, so it seems cmd_per_lun=3 is more appropriate value as in other existing FC HBA.
