The SMC protocol [1] uses a rendezvous protocol to negotiate SMC capability between peers. The current Linux implementation does not yet use this rendezvous protocol and, thus, is not compliant to RFC7609 and incompatible with other SMC implementations like in zOS. This patch adds support for the SMC rendezvous protocol. It uses a new TCP experimental option. With this option, SMC capabilities are exchanged between the peers during the TCP three way handshake.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
