Pretty big, I imagine.

Why is it a SCSI driver rather
than SATA?

It's "server" SAS hardware, a la mvsas driver. SAS hardware is that "lovely" superset of SATA + SCSI, where SATA is one of several frame formats the device may speak. So it is definitely a SCSI driver, that hooks into SATA processing via ata_sas_* hooks and functions.

Why is it so f&*%ing big?

1. Because it's a SAS driver :)

2. Because it used to be an ugly vendor driver, now in the process of being cleaned up, rather than a nice, clean from-scratch Linux driver.

So it's a bit of a tough call. It still needs more hammering and cleaning, but if this is what winds up on all Intel "server" boards that makes it pretty important.
