* External MBUFs. The card needs a lot of mbufs in the pools for high
* performance. The problem with using mbufs directly is that we would need
* a dmamap for each of the mbufs. This can exhaust iommu space on the sparc
* and it eats also a lot of processing time. So we use external mbufs
* for the small buffers and clusters for the large buffers.
* For receive group 0 we use 5 ATM cells, for group 1 one (52 byte) ATM
* cell. The mbuf storage is allocated pagewise and one dmamap is used per
* page.
*
* The handle we give to the card for the small buffers is a word combined
* of the page number and the number of the chunk in the page. This restricts
* the number of chunks per page to 256 (8 bit) and the number of pages to
* 65536 (16 bits).
*
* A chunk may be in one of three states: free, on the card and floating around
* in the system. If it is free, it is on one of the two free lists and
* start with a struct mbufx_free. Each page has a bitmap that tracks where
* its chunks are.
*
* For large buffers we use mbuf clusters. Here we have two problems: we need
* to track the buffers on the card (in the case we want to stop it) and
* we need to map the 64bit mbuf address to a 26bit handle for 64-bit machines.
* The card uses the buffers in the order we give it to the card. Therefor
* we can use a private array holding pointers to the mbufs as a circular
* queue for both tasks. This is done with the lbufs member of softc. The
