[OT] Re: 3com Driver and the 3XP Processor
Insteresting that this thread fell into this. I just had one of those cards that came across my desk phreak out. It was 2 days old and placed in a win2k server. Last night it started dumping errors about firmware and bad microcde. Have yet to test it out on another machine, but I beleive the card went bad. first 3com I have had go bad and first card I have ever had go bad inside of 2 days :) > I've installed several thousand 3com cards of variousages and types. > I've had less than 20 bad cards. > Nick Brent Norris Executive Advisor -- WKU-Linux - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Re: 3com Driver and the 3XP Processor
So it would seem. Here is the polite message I received in response my inquiry regarding the crypto interface to the card: Thank you for your inquiry. We do not offer the technical spec;s for the IPSec features of this NIC, due to the intellectual property-heavy nature of this product. We will, however, be releasing a Linux driver which supports this feature in the very near future under the beta section of our support site. The base driver for the 990 will be open source, the advanced driver (offloads, etc.) will not be open source. Hope that somewhat helps you.

Insteresting that this thread fell into this. I just had one of those cards that came across my desk phreak out. It was 2 days old and placed in a win2k server. Last night it started dumping errors about firmware and bad microcde. Have yet to test it out on another machine, but I beleive the card went bad. first 3com I have had go bad and first card I have ever had go bad inside of 2 days :) I've installed several thousand 3com cards of variousages and types.

Re: 3com Driver and the 3XP Processor
I think that they are relatively friendly. However, if they publish the interface to their card another company could come along with a card with the same functionality and take advantage of pre-existing drivers and undercut their price, thus taking away their margins. At least that is the rationale I have been given and this has occurred on at least one occasion to Adaptec. My opinion is that if you have to obscure your interface to protect your margins because you are making a commodity component then you are in the wrong business. Nonetheless they can correctly point out that they are still making a lot more money than I am :-). -Kip On Mon, 11 Jun 2001, Brent D.
