From e865f83d3064f0e9dddd47513282ae012e7576c3 Mon Sep 17 00:00:00 2001 From: Beniamino Galvani Date: Mon, 1 Jul 2019 13:45:27 +0200 Subject: device: ppp: check that connection has a PPPoE parent NMDevicePPP only handles connections with the pppoe.parent property set. match_connection() already checks this when we creating a new device. We should also perform the same check in check_connection_compatible().
