One would seem to be the buffer list itself, which also needs to fit within a 40-bit mask with 256 alignment (rxq->bd), the rb_stts needs 16-byte alignment which probably is always satisfied, but I'm not sure, you'll need to research the alignment guarantees. Another, different, question: I don't see where the driver tells the hardware how large the buffers are it allocated. Can you point me to that? You can switch 4k/8k ampdu but I don't see where you tell the hardware. johannes
