[PATCH v11 2/6] fff-support: Update PoE passthrough code

Adrian Schmutzler freifunk at adrianschmutzler.de
Mi Okt 18 23:30:54 CEST 2017


This implements an upgrade safe solution for the PoE passthrough
on multiple devices. Since LEDE already provides the relevant
settings, a check whether those are in place enables both
identification of affected devices and automatic deactivation
if parameters are changed.
