# cue.4

`cue` — CATC USB-EL1210A USB 以太网驱动

## 名称

`cue`

## 概要

`若要将此驱动编译进内核，请在内核配置文件中加入以下行：`

> device uhci device ohci device usb device miibus device uether device cue

`或者，若要在引导时以模块方式加载此驱动，请在 loader.conf(5) 中加入以下行：`

```sh
if_cue_load="YES"
```

## 描述

`cue` 驱动为基于 Computer Access Technology Corporation USB-EL1210A 芯片组的 USB 以太网适配器提供支持。

USB-EL1210A 支持 512 位多播哈希过滤器、用于站点地址的单个完美过滤项以及混杂模式。数据包通过独立的 USB 批量传输端点进行接收和发送。

CATC 芯片组仅支持 10Mbps 半双工模式，因此没有可选择的 Fn ifmedia 模式。

有关配置此设备的更多信息，请参见 [ifconfig(8)](/man/man8/ifconfig.8.md)。

## 硬件

`cue` 驱动支持基于 CATC USB-EL1210A 的 USB 以太网适配器，包括：

* Belkin F5U011/F5U111
* CATC Netmate
* CATC Netmate II
* SmartBridges SmartLink

## 诊断

* cue%d: watchdog timeout 一个数据包已排队等待传输并且已发出传输命令，但设备在超时之前未能确认传输。
* cue%d: no memory for rx list 驱动未能为接收环分配一个 mbuf。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/cue.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
