Add vendor unique experimental options area in clc handshake. In clc accept and confirm msg, vendor unique experimental options use the 16-Bytes reserved field, which defined in struct smc_clc_fce_gid_ext in previous version. Because of the struct smc_clc_first_contact_ext is widely used and limit the scope of modification, this patch moves the 16-Bytes reserved field out of struct smc_clc_fce_gid_ext, and followed with the struct smc_clc_first_contact_ext in a new struct names struct smc_clc_first_contact_ext_v2x. For SMC-R first connection, in previous version, the struct smc_clc_ first_contact_ext and the 16-Bytes reserved field has already been included in clc accept and confirm msg. Thus, this patch use struct smc_clc_first_contact_ext_v2x instead of the struct smc_clc_first_ contact_ext and the 16-Bytes reserved field in SMC-R clc accept and confirm msg is compatible with previous version. For SMC-D first connection, in previous version, only the struct smc_ clc_first_contact_ext is included in clc accept and confirm msg, and the 16-Bytes reserved field is not included. Thus, when the negotiated smc release version is the version before v2.1, we still use struct smc_clc_first_contact_ext for compatible consideration. If the negotiated smc release version is v2.1 or later, use struct smc_clc_first_contact_ ext_v2x instead.

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.
