Usually, you need to set them up last to first so that the chip doesn't see a half-filled-in set of TX descriptors. Ie. the core question is if the chip can scan the TX descriptors looking for valid ones all on it's own after processing existing TX descriptors, or do you have to explicitly allow the chip look at the newly added TX descriptor with a register write or similar? - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
