- * Top layer of the SCSI driver: interface with the MI.
- * This file contains operations specific to CPU-like devices.
- *
- * We handle here the case of other hosts that are capable of
- * sophisticated host-to-host communication protocols, we make
- * them look like... you'll see.
- *
- * There are two sides of the coin here: when we take the initiative
- * and when the other host does it. Code for handling both cases is
- * provided in this one file.
