|
|
* Broadcom BCM570x family gigabit ethernet driver for FreeBSD.
|
|
*
|
|
* The Broadcom BCM5700 is based on technology originally developed by
|
|
* Alteon Networks as part of the Tigon I and Tigon II gigabit ethernet
|
|
* MAC chips. The BCM5700, sometimes referred to as the Tigon III, has
|
|
* two on-board MIPS R4000 CPUs and can have as much as 16MB of external
|
|
* SSRAM. The BCM5700 supports TCP, UDP and IP checksum offload, jumbo
|
|
* frames, highly configurable RX filtering, and 16 RX and TX queues
|
|
* (which, along with RX filter rules, can be used for QOS applications).
|
|
* Other features, such as TCP segmentation, may be available as part
|
|
* of value-added firmware updates. Unlike the Tigon I and Tigon II,
|
|
* firmware images can be stored in hardware and need not be compiled
|
|
* into the driver.
|
|
*
|
|
* The BCM5700 supports the PCI v2.2 and PCI-X v1.0 standards, and will
|
|
* function in a 32-bit/64-bit 33/66Mhz bus, or a 64-bit/133Mhz bus.
|
|
*
|
|
* The BCM5701 is a single-chip solution incorporating both the BCM5700
|
|
* MAC and a BCM5401 10/100/1000 PHY. Unlike the BCM5700, the BCM5701
|
|
* does not support external SSRAM.
|
|
*
|
|
* Broadcom also produces a variation of the BCM5700 under the "Altima"
|
|
* brand name, which is functionally similar but lacks PCI-X support.
|
|
*
|
|
* Without external SSRAM, you can only have at most 4 TX rings,
|
|
* and the use of the mini RX ring is disabled. This seems to imply
|
|
* that these features are simply not available on the BCM5701. As a
|
|
* result, this driver does not implement any support for the mini RX
|
|
* ring.

|
|
*
|
|
* Jumbo Receive Producer Ring
|
|

* frames (i.e. anything bigger than the "standard" frames)
|
|
* to the controller.
|
|
*
|
|
* Mini Receive Producer Ring
|
|
* - This ring is used to feed receive buffers for "mini"
|
|
* sized frames to the controller.
|
|
* - This feature required external memory for the controller
|
|
* but was never used in a production system. Should always
|
|
* be disabled.
|
|
*
|
|
* Receive Return Ring
|
|
* - After the controller has placed an incoming frame into a
|
|
* receive buffer that buffer is moved into a receive return
|
|
* ring. The driver is then responsible to passing the
|
|
* buffer up to the stack. Many versions of the controller
|
|
* support multiple RR rings.
|
|
*
|
|
* Send Ring
|
|

* the controller support multiple send rings.
