Why I did it The S3IP (Simplified Switch System INtegration Program) sysfs specification defines a unified interface to access peripheral hardware on devices from different vendors, making it easier for SONiC to support different devices and platforms. PDDF is a framework to simplify the driver and SONiC platform APIs development for new platforms. This effort is first step in combining the two frameworks. This specific PR adds support for pddf-s3ip-init.service and enables it in PDDF.
