I was wonding if it would be better to have the ->enqueue() perform the mapping operation, store the queue index selected inside of the skb, and just use the normal ->hard_start_xmit() to send the packet out? The only thing to take care of is the per-queue locking, but that should be easily doable. We might be able to do this even without making sk_buff any larger. For example, I suppose skb->priority might be deducable down to a u16. After a quick audit I really cannot see any legitimate use of anything larger than 16-bit values, but a more thorough audit would be necessary to validate this. - 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/
