Hi, I'm trying to solve a problem of delay on a routing box that uses two ethernet interfaces. Ususally, everything is fine and the box forwards frames within 1 or 2 ms. But occasionnally the last frame of a burst is not sent until new traffic enters the box, as if this frame had to be pushed at some stage. I believe that Tx fifo waits for a threshold before starting, or sends immediatly a frame if it is complete, rigth ? Any ideas on the subject are welcome Fabien - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
