As an enhancement to distribute requests to multiple hardware queues, add the infrastructure to hash a SCSI command into a particular hardware queue. Support the following scenarios when deriving which queue to use: single queue, tagging when SCSI-MQ enabled, and simple hash via CPU ID when SCSI-MQ is disabled. Rather than altering the existing send API, the derived hardware queue is stored in the AFU command where it can be used for sending a command to the chosen hardware queue. Signed-off-by: Matthew R.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
