Looks good Not use yet
Install confgd microUSB to Eth automatically Tried several apps dedicated to finding installing or running micro USB to Ethernet. Uninstalled and tried this, and although it was for ADB, it brought my single online and grabbed a DHCP address (other apps I had to manually enter IP info).
+ autostart at boot option (requires NEW permission RECEIVE_BOOT_COMPLETED)
* use better ip detection logic (fixes ip detection on marshmallow and higher)
* fix NPE when root access is denied
