linux/drivers/scsi/qla2xxx/qla_dbg.c
Andrew Vasquez a7a167bf7e [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.
