In the conversion into a tunable, we converted the size of the s/g list used by the driver to be based off of a hardcoded size of 128k rather than maxphys, this caused performance problems for us. Revert this to use the maxphys tunable. Note that this constant is used to size dynamically allocated things, and not static data structs, so this is safe.

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.
