- * SX8 hardware has a single message queue for all ATA ports.

- * corrupt data eventually, if more than one request was outstanding.
- * As one can imagine, having 8 ports bottlenecking on a single
- * command hurts performance.
- *
- * Based on user reports, later versions of the hardware (firmware?)
- * seem to be able to survive with more than one command queued.
- *
- * Therefore, we default to the safe option -- 1 command -- but
- * allow the user to increase this.
- *
- * SX8 should be able to support up to ~60 queued commands (CARM_MAX_REQ),
- * but problems seem to occur when you exceed ~30, even on newer hardware.
