From 79f89a4296ff22f09baf538d4ff2a6d0c3097a73 Mon Sep 17 00:00:00 2001 From: "andrew.vasquez@qlogic.com" Date: Fri, 13 Jan 2006 17:05:58 -0800 Subject: [SCSI] qla2xxx: Disable port-type RSCN handling via driver state-machine. Given the semantic changes in both the device-model and fc-transport APIs, the driver's handling of port-type RSCNs via a series of ADISCs and PLOGIs can cause series of badness ranging from unexpectedly device loss to devices not being discovered. In the interim, disable (via a module-parameter) this feature and allow RSCN management to continue to occur within the driver's DPC thread.
