[SCSI] lpfc 8.3.21: RRQ Implementation fixes
RRQ Implementation fixes
- Added checks to prevent a call to findnode_did in clr_active_rrq
- Added the del_sync_timer call for the rrq_tmr to the stop_hba_timers routine.
- Added a check in __lpfc_set_active_rrq for the driver unloading to prevent
adding an rrq when the driver is being removed.
- Add code to scsi_iocb_cmpl to check for the remote stop and add the rrq.
- Added the same check to els retry.
- Added code to compare the source did in the els rrq to the vports did and
chose the right exchange ID.
- Initialize the start_cmd pointer to indicate when we have looped through
all of the scsi buffers.
- Remove the need for the lock around the clearing of the active bit in the
rrq.
- Added code to clean the els and fcp xri aborted list and remove the all of
the RRQs for a deleted vport.
