Subject: [PATCH] Send PADT on PPPoE disconnect
Once we've terminated the PPP session, there is no chance of a PPP layer
disconnect. Some PPPoE relays don't detect the PPP session going down, and
depend on a long timeout or a PPPoE PADT to terminate the session.
Send a PADT on disconnect to work around these buggy relays.
