37 * Broadcom BCM570x family gigabit ethernet driver for FreeBSD.

43/*
44 * The Broadcom BCM5700 is based on technology originally developed by
45 * Alteon Networks as part of the Tigon I and Tigon II gigabit ethernet
46 * MAC chips. The BCM5700, sometimes refered to as the Tigon III, has
47 * two on-board MIPS R4000 CPUs and can have as much as 16MB of external
48 * SSRAM. The BCM5700 supports TCP, UDP and IP checksum offload, jumbo
49 * frames, highly configurable RX filtering, and 16 RX and TX queues
50 * (which, along with RX filter rules, can be used for QOS applications).
51 * Other features, such as TCP segmentation, may be available as part
52 * of value-added firmware updates. Unlike the Tigon I and Tigon II,
53 * firmware images can be stored in hardware and need not be compiled
54 * into the driver.
55 *
56 * The BCM5700 supports the PCI v2.2 and PCI-X v1.0 standards, and will
57 * function in a 32-bit/64-bit 33/66Mhz bus, or a 64-bit/133Mhz bus.
58 *
59 * The BCM5701 is a single-chip solution incorporating both the BCM5700
60 * MAC and a BCM5401 10/100/1000 PHY. Unlike the BCM5700, the BCM5701
61 * does not support external SSRAM.
62 *
63 * Broadcom also produces a variation of the BCM5700 under the "Altima"
64 * brand name, which is functionally similar but lacks PCI-X support.
65 *
66 * Without external SSRAM, you can only have at most 4 TX rings,
67 * and the use of the mini RX ring is disabled. This seems to imply
68 * that these features are simply not available on the BCM5701. As a
69 * result, this driver does not implement any support for the mini RX
70 * ring.

773 * This is really a bit of a kludge. We allocate a special
774 * jumbo buffer pool which (thanks to the way our DMA
775 * memory allocation works) will consist of contiguous
776 * pages. This means that even though a jumbo buffer might
777 * be larger than a page size, we don't really need to
778 * map it into more than one DMA segment. However, the
779 * default mbuf tag will result in multi-segment mappings,
780 * so we have to create a special jumbo mbuf tag that
781 * lets us get away with mapping the jumbo buffers as
782 * a single segment. I think eventually the driver should
783 * be changed so that it uses ordinary mbufs and cluster
784 * buffers, i.e. jumbo frames can span multiple DMA
785 * descriptors. But that's a project for another day.
