Should driver allocate extra memory for the packets needs buffered? If I understand your question correctly, there is nothing special that you need to do. The driver owns the SKB once it's passed in to your transmit function; you are free to hang onto it for a while if that's what you need to do. You'll want to take care not to stop the queue while holding packets, but I assume you've thought of that. jon
