scsi: mpt3sas: Do not use 32-bit atomic request descriptor for Ventura controllers.
Sending I/O through 32 bit descriptors to Ventura series of controller results in IO timeout on certain conditions. This error only occurs on systems with high I/O activity. Changes in this patch will prevent driver from using 32 bit descriptor and use 64 bit Descriptors Signed-off-by: Suganath Prabu S <suganath-prabu.subramani@broadcom.com> Reviewed-by: Tomas Henzl <thenzl@redhat.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Signed-off-by: Martin K.
