[ Upstream commit 67f471b6ed3b09033c4ac77ea03f92afdb1989fe ] This patch fixes a long-standing bug that initialized the FC-NVME cmnd iu CSN value to 1. Early FC-NVME specs had the connection starting with CSN=1. By the time the spec reached approval, the language had changed to state a connection should start with CSN=0. This patch corrects the initialization value for FC-NVME connections. Additionally, in reviewing the transport, the CSN value is assigned to the new IU early in the start routine. It's possible that a later dma map request may fail, causing the command to never be sent to the controller. Change the location of the assignment so that it is immediately prior to calling the lldd. Add a comment block to explain the impacts if the lldd were to additionally fail sending the command.

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.
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.
