38 * Broadcom BCM57xx(x)/BCM590x NetXtreme and NetLink family Ethernet driver
40 * The Broadcom BCM5700 is based on technology originally developed by
41 * Alteon Networks as part of the Tigon I and Tigon II Gigabit Ethernet
42 * MAC chips. The BCM5700, sometimes referred to as the Tigon III, has
43 * two on-board MIPS R4000 CPUs and can have as much as 16MB of external
44 * SSRAM. The BCM5700 supports TCP, UDP and IP checksum offload, jumbo
45 * frames, highly configurable RX filtering, and 16 RX and TX queues
46 * (which, along with RX filter rules, can be used for QOS applications).
47 * Other features, such as TCP segmentation, may be available as part
48 * of value-added firmware updates. Unlike the Tigon I and Tigon II,
49 * firmware images can be stored in hardware and need not be compiled
52 * The BCM5700 supports the PCI v2.2 and PCI-X v1.0 standards, and will
53 * function in a 32-bit/64-bit 33/66Mhz bus, or a 64-bit/133Mhz bus.
55 * The BCM5701 is a single-chip solution incorporating both the BCM5700
56 * MAC and a BCM5401 10/100/1000 PHY. Unlike the BCM5700, the BCM5701
57 * does not support external SSRAM.
59 * Broadcom also produces a variation of the BCM5700 under the "Altima"
60 * brand name, which is functionally similar but lacks PCI-X support.
62 * Without external SSRAM, you can only have at most 4 TX rings,
63 * and the use of the mini RX ring is disabled. This seems to imply
64 * that these features are simply not available on the BCM5701. As a
65 * result, this driver does not implement any support for the mini RX

2056 * Receive Return Ring
2057 * - After the controller has placed an incoming frame into a
2058 * receive buffer that buffer is moved into a receive return
2059 * ring. The driver is then responsible to passing the
2060 * buffer up to the stack. Many versions of the controller
