This is still a problem with 1.8.1b540; in fact the counters are completely broken with PPPoE.
In/out packets 0/0 (3.25 MB/0 bytes)
In/out errors 0/1493584607
In/out packets does not seem to do anything, out errors counters grows like mad every time the status page is reloaded. There are no network problems for sure, the VDSL connection works perfectly fine (~25Mbps downlink, ~2Mbps uplink).
Additionally:
Status up
PPPoE up
MAC address 3544447
Huh?
