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(). Fixes:6c3195931e('core: implement activation of PPP devices') https://gitlab.freedesktop.org/NetworkManager/NetworkManager/issues/203 (cherry picked from commit17f4a1e794) (cherry picked from commit5ca888d693)
