reset device task request from the driver. If the drive fails to respond with a signature FIS, the driver would previously get into an endless retry loop, stalling all I/O to the drive and keeping user processes stranded. Instead, fail the i/o and invalidate the device if the task management command times out. This is controllable with the sysctl and tunable hw.isci.fail_on_task_timeout dev.isci.0.fail_on_task_timeout The default for these is 1. Reviewed by: jimharris Obtained from: Netflix, Inc.

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.
