The user framework module complies with s3ip sysfs specification (#12894)
Why I did it The user framework module complies with s3ip sysfs specification How I did it 1、 create a s3ip_sysfs service 2、 the s3ip_sysfs service call the “s3ip_sysfs_tool.sh” to install kernel module and run s3ip_load.py 3、 s3ip_load.py will parse the s3ip_sysfs_conf.json configuration file and create /sys_switch/ directory How to verify it A demo driver base on this framework will display the sysfs node wich conform to the s3ip sysfs specification
