[SCSI] qla2xxx: Remove unused port-type RSCN handling code.
Expandind on the previous commit:
commit 79f89a4296
Author: andrew.vasquez@qlogic.com <andrew.vasquez@qlogic.com>
Date: Fri Jan 13 17:05:58 2006 -0800
[SCSI] qla2xxx: Disable port-type RSCN handling via driver state-machine.
and given:
- the process-context requirements of the FC transport
rport-APIs.
- lack of port-type RSCN processing logic for ISP24xx and newer
chips.
it's time now to remove the state-machine logic from mainline.
