Making support for ADSL interface ??
Hi Everybody, I would like to inquire about what it would take to make a driver for a specific ADSL board with direct PCI interface to FreeBSD First, lets assume that I will supply boards, and that all necessery documentation will be available. How good is FreeBSD current structures for running ADSL, I'm thinking about the ATM support already present, and probably using netgraph ? I would need support for the most common protocols used worldwide, t.ex PPPoATM, IPoATM Next, is there any takers for doing the actual work ? I would probably need somebody who has some knowledge about ADSL and ATM, and have access to some equipment and/or lines for testing. I will probably be able to offer some limited payment for the work, the driver will probably be possible to release under BSD license, and the resulting hardware will be available at low cost.

I would need support for the most common protocols used worldwide, t.ex PPPoATM, IPoATM You'd also need to support PPPoE, which on most ADSL systems appears as PPP on Ethernet as RFC-1490 bridged encapsulation of the ethernet frames in AAL5 ATM cells. It's unclear that this is worth doing at the ATM level since the CPE devices with an Ethernet are fairly inexpensive; the existing Ethernet interface might be the most cost effective. There's also limited standardization on management interfaces for ADSL CPE equipment. It's been a couple of years since I've been involved with the ADSL forum, but there were proposes to have some management channel to the CPE device (perhaps using ILMI? I don't recall).

I will need to support PPPoE, but netgraph can probably take care of that But directly, as the point is to have one single low cost box with everything, that why I'm working on doing an ADSL board with PCI interface And I might even put the ADSL interface on the mainboard.

The configuration and management have moved forward, take a look at the DSL Forum TR-037 Regards, Søren To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

What I'm not sure is if the netgraph code currently has hooks into the ATM network interfaces, and if it knows about ethernet frame bridge encapsulation. I'm guessing that the netgraph platform would make the most sense to support this kind of application. louie To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

I have unsuccessfully discussed writing drivers for ADSL cards with several vendors (alcatel, adi, efficient) but no one have not had courage to give out real information. Even released linux drivers are mostly fakes - some kernel modules providing ioctl interface for binary only userland parts. When driver for hardware is available, I believe, that then freebsd community has enough people to develop surrounding infrastructure further.

If only someone would provide microcode and little bit additional information for compleating driver for efficient 3060/3061 pci cards (http://home.uninet.ee/~taavi/lanai/) :) To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message
