2019-03-27scsi: qedf: Correct xid range overlap between offloaded requests and libfc ↵Chad Dupuis
requests There is currently an overlap where exchange IDs between what is used for offloaded commands and by libfc for ELS commands. Correct this so that exchange ID range is: Offloaded requests: 0 to 0xfff libfc requests: 0x1000 to 0xfffe Signed-off-by: Chad Dupuis <cdupuis@marvell.com> Signed-off-by: Saurav Kashyap <skashyap@marvell.com> Signed-off-by: Martin K.
