Thanks for your advice! Adding 'set link max-redial -1' to mpd.conf
solved the problem. Looks like lcp on mpd side was trying to redial
but kept failing because PPPoE session wasn't present. Unn, it makes
sense..

The only problem I am seeing is proxy arp entry still left on the host
after PPPoE session is terminated. I think it should be automatically
removed when IPCP goes down.
