PPPoE problem

Hello everyone!

I'm using FreeBSD-4.8.
I'm running ADSL card using ppp and kernel NETGRAPH implementation.

Without any changes to the kernel, I was not able to connect to the provider. This is the trace that I got from my driver:

You can find that PADR packet includes AC-Name Tag (as I found later it cause the problem).

I went to NETGRAPH source and comment the follow lines that add AC-Name tag to PADR packet:

	if ((tag=get_tag(ph, PTT_AC_NAME))){
		insert_tag(sp, tag);
		send_acname(sp, tag);
	}

Now, when I run ppp+dial I was able to connect to the provider and the trace is follow:
