From a7a167bf7e2d196fc33f292e7b02e90fee03bc9a Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Fri, 23 Jun 2006 16:10:29 -0700 Subject: [SCSI] qla2xxx: Rework firmware-trace facilities. - Defer firmware dump-data raw-to-textual conversion to user-space. - Add module parameter (ql2xallocfwdump) to allow for per-HBA allocations of firmware dump memory. - Dump request and response queue data as per firmware group request. - Add extended firmware trace support for ISP24XX/ISP54XX chips.
