    Yes, I know about it. It will occur for any device
    which must use linear RX buffers and supports
    >PAGE_SIZE MTUs.

    But modern chips are going to support segmentation of
    receive packets into multiple individual pages and
    therefore not have this order>0 page allocation
    requirement.

    That is my point.
