From 4da26e162b69d89c3186a35a052c05e61a555637 Mon Sep 17 00:00:00 2001 From: Chad Dupuis <chad.dupuis@qlogic.com> Date: Fri, 15 Oct 2010 11:27:40 -0700 Subject: [PATCH] [SCSI] qla2xxx: Add module parameter to enable/disable GFF_ID device type check. Add the module parameter ql2xgffidenable to disable/enable the use of the GFF_ID name server command to prevent non FCP SCSI devices from being added to the driver's internal fc_port database.
