[LEDE-DEV] [PATCH][RFC] procd: service: add data within the service itself

pme.lebleu at gmail.com pme.lebleu at gmail.com
Wed Oct 4 03:50:59 PDT 2017


From: Pierre Lebleu <pme.lebleu at gmail.com>

It gives the ability to create firewall data within the
service itself rather than within an instance.
