This was logged now: (all at May 6 05:34:50 2020 UTC) pppoe_disc_rcv PADT received, sid=1, SRC: a4:7b:2c:9e:c7:44, DST: 44:4e:6d:fd:c7:39 pppoe_disc_rcv PADT received, own hw addr: c4:XX:XX:XX:XX:ed dev eth1.3902, flags: 0x1003, promiscuity 0 pppoe_disc_rcv PADT received, not four our address, ignoring (the last line is from my fix, the connection is now not dropped when the PADT is not for us; works fine, my connection stays up and working) I'll clean up and post the patch later.
