The ioctl to set ppp parameters failed. Probably because of this:

Needs root, and you want the pppoe interface not the device it's running
over.
There was a suggestion to destroy the interface. down+up should be enough,
but if you do have to destroy it, you'll often reconnect more quickly if you
have disconnected properly with "ifconfig pppoe0 down".
