This reverts commitb8baac3b9c. IPv4 packets with no DF flag set on result in frequent flow entry teardown cycles, this is visible in the network topology that is used in the nft_flowtable.sh test. nft_flowtable.sh test ocassionally fails reporting that the dscp_fwd test sees no packets going through the flowtable path.

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.
