Hi, In our driver, we have 4k receive buffers, but usually ~1500 byte packets. How do other drivers handle this? We currently set up the truesize of each SKB to be its size plus the 4k page size, but we see performance improvements when we lie and pretend the truesize is just 4k/(# of packets in the page), which is correct as long as the packets are all pending in the stack since they share the page. How do other drivers handle this? Should the truesize maybe be aware of this kind of sharing? Should we just lie about it and risk that the truesize is accounted erroneously if some but not all of the packets are freed?
