Hi Sekar,
linux-can mailing list is related to the CAN bus (Controller Area
Network) - you probably did not want to post here, right? ;-)
Regards,
Oliver

Probably not, but I'll give a try.

PADT is the PPPoE termination message. It means that your peer has
decided to close the session. It could do so for any of a wide number
of reasons, and this doesn't seem to indicate any details. For example,
your peer:
- may be rebooting or administratively disabled
- may have a session time limit that's enforced by shutdown
- may have a bug that causes the session to crash
- may have detected some configuration problem
- may have some other internal limitation
It's really not clear without getting information from the peer. You
might possibly try getting a tcpdump (or wireshark) trace on the
Ethernet interface over which PPPoE is being run, and that might help
reveal the events surrounding the connection closure.

Looks like all is working as expected following a disconnect by the peer.

Are you really running a PPPoE server? I had expected that you were
running a client.
What exactly are you doing with PPPoE? In general, if you're trying to
connect to your ISP, then at least "require-chap" and "login" are wholly
inappropriate. They demand that your peer identify itself to you --
which ISPs almost never do -- and weirdly ask to use both CHAP and local
authentication, a combination that's _fundamentally_ impossible because
CHAP doesn't reveal the passphrase on the wire. Whoever set up those
options was probably pretty confused.
If you can do so, I suggest running with "debug" and "updetach" options,
and forwarding the complete trace output to the list. If there's a
problem with pppd configuration (as opposed to PPPoE or some other
issue), that should help reveal what's going on at the PPP level.
