Implement support for the new DSCP selector that allows IPv4 FIB rules to match on the entire DSCP field, unlike the existing TOS selector that only matches on the three lower DSCP bits. Differentiate between both selectors by adding a new bit in the IPv4 FIB rule structure (in an existing one byte hole) that is only set when the 'FRA_DSCP' attribute is specified by user space. Reject rules that use both selectors.

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.
