610 * pages. This means that even though a jumbo buffer might
611 * be larger than a page size, we don't really need to
612 * map it into more than one DMA segment. However, the
613 * default mbuf tag will result in multi-segment mappings,
614 * so we have to create a special jumbo mbuf tag that
615 * lets us get away with mapping the jumbo buffers as
616 * a single segment. I think eventually the driver should
617 * be changed so that it uses ordinary mbufs and cluster
618 * buffers, i.e. jumbo frames can span multiple DMA
619 * descriptors. But that's a project for another day.
623 * Create DMA stuffs for jumbo RX ring.
