Ido Schimmel says: ==================== net: fib_rules: Add DSCP mask support In some deployments users would like to encode path information into certain bits of the IPv6 flow label, the UDP source port and the DSCP field and use this information to route packets accordingly. Redirecting traffic to a routing table based on specific bits in the DSCP field is not currently possible. Only exact match is currently supported by FIB rules. This patchset extends FIB rules to match on the DSCP field with an optional mask. Patches #1-#5 gradually extend FIB rules to match on the DSCP field with an optional mask. Patch #6 adds test cases for the new functionality. iproute2 support can be found here [1].

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.
