Aleksei Oladko 9681522062 selftests: forwarding: vxlan_bridge_1d_ipv6: fix test failure with br_netfilter enabled 
[ Upstream commit ce9f6aec0f ]

The test generates VXLAN traffic using mausezahn, where the encapsulated
inner IPv6 packet has an incorrect payload length set in the IPv6 header.
After VXLAN decapsulation, such packets do not pass sanity checks in
br_netfilter and are dropped, which causes the test to fail.

Fix this by setting the correct IPv6 payload length for the encapsulated
packet generated by mausezahn, so that the packet is accepted
by br_netfilter.

              )"00:"$(              : ICMPv6.checksum
              )

Data after IPv6 header:
• 80: — 1 byte (ICMPv6 type)
• 00: — 1 byte (ICMPv6 code)
• 00: — 1 byte (ICMPv6 checksum, truncated)

Total: 3 bytes → 00:03 is correct. The old value 00:08 did not match
the actual payload size.

README 

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 reStructuredText 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.
