Connection creation with SMC-R starts through an internal TCP-connection. The Ethernet interface for this TCP-connection is not restricted to the Ethernet interface of a RoCE device. Any existing Ethernet interface belonging to the same physical net can be used, as long as there is a defined relation between the Ethernet interface and some RoCE devices. This relation is defined with the help of an identification string called "Physical Net ID" or short "pnet ID". Information about defined pnet IDs and their related Ethernet interfaces and RoCE devices is stored in the SMC-R pnet table. A pnet table entry consists of the identifying pnet ID and the associated network and IB device. This patch adds pnet table configuration support using the generic netlink message interface referring to network and IB device by their names. Commands exist to add, delete, and display pnet table entries, and to flush or display the entire pnet table. There are cross-checks to verify whether the ethernet interfaces or infiniband devices really exist in the system. If either device is not available, the pnet ID entry is not created. Loss of network devices and IB devices is also monitored; a pnet ID entry is removed when an associated network or IB device is removed.

README
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.
