Caleb Sander 29e80d7964 nvme-tcp: fix nvme_tcp_term_pdu to match spec
[ Upstream commit aa01c67de5 ]

The FEI field of C2HTermReq/H2CTermReq is 4 bytes but not 4-byte-aligned
in the NVMe/TCP specification (it is located at offset 10 in the PDU).
Split it into two 16-bit integers in struct nvme_tcp_term_pdu
so no padding is inserted. There should also be 10 reserved bytes after.
There are currently no users of this type.

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.
