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

1986 * ring. The driver is then responsible to passing the
