by treating it as UDMA. This fixes a problem introduced in r249933/r249939, where CAM sends ATA_DSM_TRIM to SATA devices using ATA_PASSTHROUGH_16. scsi_ata_trim() sets protocol as DMA (not UDMA) which is for multi-word DMA, even though no such mode is selected for the device. isci(4) would fail these commands which is the correct behavior but not consistent with other HBAs, namely LSI's. smh@ did some further testing on an LSI controller, which rejected ATA_PASSTHROUGH_16 commands with mode=UDMA_OUT, even though only a UDMA mode was selected on the device. So this precludes adding any kind of mode detection in CAM to determine which mode to use on a per-device basis.

FreeBSD Driver for Intel(R) C600 SAS Controller =============================================== This driver has been developed for use with FreeBSD, version 9.0 and later. This driver uses an OS-agnostic abstraction layer library named SCIL that is published by Intel specifically for the C600 SAS controller. The SAS controller has no firmware, so the driver is extensive and using SCIL minimizes the development and maintenance cost of the driver. The FreeBSD implementation files are in the isci directory, and SCIL files are in the isci/scil subdirectory. As Intel publishes new versions of SCIL (to add features or fix bugs), the isci/scil subdirectory will be updated appropriately.
