Linux kernel stable tree

Implement support for MQ in fnic driver: The block multiqueue layer issues IO to the fnic driver with an MQ tag. Use the mqtag and derive a tag from it. Derive the hardware queue from the mqtag and use it in all paths. Modify queuecommand to handle mqtag. Replace wq and cq indices to support MQ. Replace the zeroth queue with a hardware queue. Implement spin locks on a per hardware queue basis. Replace io_lock with per hardware queue spinlock. Implement out of range tag checks. Allocate an io_req_table to track status of the io_req. Test the driver by building it, loading it, and configuring 64 queues in UCSM. Issue IOs using Medusa on multiple fnics. Enable/disable links to exercise the abort and clean up path.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
