Ido Schimmel says: ==================== selftests: forwarding: Add tests for VXLAN routing VXLAN routing allows hosts in different overlay networks (i.e., different VNIs) to communicate with one another. Two popular routing models are asymmetric and symmetric routing. In asymmetric routing the ingress VTEP routes the packet into the correct VXLAN tunnel, whereas the egress VTEP only bridges the packet to the correct host. Therefore, packets in different directions use different VNIs - the target VNI. In symmetric routing both the ingress and egress VTEPs perform routing in the overlay network into / from the VXLAN tunnel. Packets in different directions use the same VNI - the L3 VNI. Different tenants (VRFs) use different L3 VNIs. Patch #1 adds a test for asymmetric routing. Patches #2-#3 reuse the topology and add test cases for ARP decapsulation and suppression. Patch #4 adds a test for symmetric routing. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
