[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. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
