[PATCH 6/8] selftests: netfilter: add MTU arguments to flowtables

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2020-08-15 22:19:01
Also in: netfilter-devel
Subsystem: kernel selftest framework, the rest · Maintainers: Shuah Khan, Shuah Khan, Linus Torvalds 

From: Fabian Frederick <redacted>

Add some documentation, default values defined in original
script and Originator/Link/Responder arguments
using getopts like in tools/power/cpupower/bench/cpufreq-bench_plot.sh
