The API for the 200E line of adapters is available as ftp://ftp.fore.com/pub/docs/port/aali.pdf. I just checked and it is dated May 1997. This document never did list what the changes from microcode rev to rev were, they simply put out a new document. Quite some time ago, Fore posted info on obtaining driver source and documentation for their new HE line of adapters. The HE is not really an API since you'd be talking straight to the adapters registers, etc. as opposed to talking to a microcode app on the 200E line. I assume someone actively doing HE development on Linux could point you to the right specs, else someone at Macroni, and if all else fails, I could go through my archives but that would take some time to do... [Having done the initial FreeBSD FORE driver, I can attempt to answer questions as my job/time permits. I do not have any access to ATM equipment which would allow me to test anything, let alone do any kind of debug/development work. Fortunately, there have been several other folks who are active on the list that have stepped up to the task so hats off to them! Did you see the comments I replied with yesterday about examining IP mbufs as they come into ipatm_output()? This would be the place to start determining who's doing the fragmenting.] Joseph Thomas -----Original Message----- From: Alex Huppenthal [mailto:alex@aspenworks.com] Sent: Friday, April 06, 2001 10:32 AM To: Archinaco, Chris Cc: freebsd-atm@FreeBSD.ORG Subject: Re: SR100069960 - Linux resources Chris, Thanks a million for this info. I'm still stuggling a bit with the BSD driver and wonder if you can shed some light on how the ForeRunner card actually operates now days. Is there a place we can look to find documentation on the API to the card? Perhaps including a list of functional changes made to PCA200E recently? I'm excited about using this card in a number of installations. Currently, the FreeBSD version of the driver seems to fragment PDUs in a way which Xedia routers (lucent) interpret as a 'tiny fragment' attack. At that point they discard the entire PDU. New development is going on and I just wonder if you have information which could verify how things work. I'm copying the group which is currently very interested in making FreeBSD a high performance platform using your ATM PCI solution. Thank you, Alex PS: to listen in on the discussion about FreeBSD and ATM..
