iptables: add systemd helper unit to load/restore rules
There is currently no way to automatically load iptables rules in OE. Add a systemd unit file to automatically load rules on network connection. This is cribbed from the way ArchLinux handles iptables with some minor modifications for OE. New rules can be generated directly on the target using: # iptables-save -f /etc/iptables/iptables.rules Good documentation for writing rules offline is lacking, but the basics are explained here: https://unix.stackexchange.com/q/400163/49405 (From OE-Core rev: 76d3574d17c38d93ba4660bdae5730ac222994d4) Signed-off-by: Jack Mitchell <jack@embed.me.uk> Signed-off-by: Diego Rondini <diego.rondini@kynetics.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
