When using if_pppoe kernel module activated through GUI option System/Advanced/Networking/Use if_pppoe kernel module for PPPoE client, no logs are writting to /var/log/ppp.log other than an occasional "failed to set default route 17 message". On disabling if_pppoe and reverting to using mpd5, logs are written again. It's been an issue in both 2.8.0 and 2.8.1

ppp.log when using if_pppoe:
Aug 13 10:32:15 kernel if_pppoe: pppoe1: failed to set default route 17
Aug 9 05:54:27 kernel if_pppoe: pppoe1: failed to set default route 17

WAN link operates correctly under both options, routing internet traffic as expected.
