	Could be, I am easily distracted ;) . I think I already agreed that for people wanting to control BDP actual packet size matters more, but forgot about that when thinking how clever the usage of skb-> truesize is. So the rephrase, skb->truesize is great if one wants to control the routers memory consumption, which is the angle I have been mainly arguing from. It seems all three ways of limiting the queue have some merit, with n_packets and consumed_memory being sort of equivalent, and byte_limit being the odd one out…
