PPPoE (STABLE 5) : two PADI packets emitted and then nothing...

[ComteZero _]

Hello,

I already posted this thread in freebsd-stable but seems that this list is 
more appropriate.

it's been two weeks I try to find out what's wrong. Clean install from cvsup 
STABLE (5).
my ADSL account works fine with REL. 4.4+rp_pppoe but not with my new STABLE 
(5) (without using rp_pppoe).
could someone help me on this issue (logs provided here, ppp.log in attached 
file)... 
two PADI are emitted but nothing happens after.
(i saw that someone had a similar problem, but with previous netgraph 
revisions).

thank you.

Since my ADSL modem is 3Com HomeConnect, I've set the 
net.graph.nonstandard_pppoe=1

ng_pppoe.c rev. is 1.67.2.1 <http://1.67.2.1/>
ng_socket.c rev. is 1.53.2.3 <http://1.53.2.3/>

my ppp.conf is :
default:
set log all
set ifaddr X.X.X.X/0 10.0.0.2/0 <http://10.0.0.2/0>

my_isp :
set device PPPoE:xl0
set authname MY_USER
set authkey MY_PWD
set dial
#set login
add default HISADDR


here is a tcpdump -vv -i xl0 :

18:48:40.808687 PPPoE PADI [Host-Uniq 0x00E654C1]
