Max Gurtovoy 33cfdc2aa6 nvme: enforce extended LBA format for fabrics metadata
An extended LBA is a larger LBA that is created when metadata associated
with the LBA is transferred contiguously with the LBA data (AKA
interleaved). The metadata may be either transferred as part of the LBA
(creating an extended LBA) or it may be transferred as a separate
contiguous buffer of data. According to the NVMeoF spec, a fabrics ctrl
supports only an Extended LBA format. Fail revalidation in case we have a
spec violation. Also add a flag that will imply on capable transports and
controllers as part of a preparation for allowing end-to-end protection
information for fabric controllers.

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.
