The card uses 21143 and seems quite reliable. I know of a bug in the code on my web site whose symptoms look like a freeze, but that is presumably related to a race in delivering softisr's and so should be card independent and appear with the fxp's as well -- as a matter of fact i first hit it with the "sis" card. cheers luigi On Sat, Feb 02, 2002 at 06:17:05PM +0100, Phil Regnauld wrote: > > Sounds good! > > We're using the code here with 5 x fxps in our firewall, and the > load on the box is ridiculously low (0.1 on average). > > We had it running with 2 x DFE 570-TX for a total of 8 ports, > but whatever we tried (including activating polling) the cards > would still go into buffer underrun, and eventually lock up. > > Until we were forced to switch to fxp, we had an ifconfig down/up > to unfreeze the cards every 5 minutes just in case :-| > > I must say I'm not really convinced about the D-Link cards...
