commit: https://git.buildroot.net/buildroot/commit/?id=4906e77d5957a78df3181a0c8a1b5f0e55ce44da
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
This patch will add an init script that allows
to set a ruleset in /etc/iptables.conf to be loaded
on boot, or flushed on stop, as well as a saving
command to generate a new file.
