Add the single subflow test case for MP_FAIL, to test the infinite mapping case. Use the test_linkfail value to make 128KB test files. Add a new function reset_with_fail(), in it use 'iptables' and 'tc action pedit' rules to produce the bit flips to trigger the checksum failures. Set validate_checksum to enable checksums for the MP_FAIL tests without passing the '-C' argument. Set check_invert flag to enable the invert bytes check for the output data in check_transfer(). Instead of the file mismatch error, this test prints out the inverted bytes. Add a new function pedit_action_pkts() to get the numbers of the packets edited by the tc pedit actions. Print this numbers to the output. Also add the needed kernel configures in the selftests config file.

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.
