# kue.4

`kue` — Kawasaki LSI KL5KUSB101B USB 以太网驱动

## 名称

`kue`

## 概要

`要将此驱动编译进内核，请在你的内核配置文件中加入以下行：`

> device uhci device ohci device usb device miibus device uether device kue

`或者，要在引导时以模块形式加载该驱动，请在 loader.conf(5) 中加入以下行：`

```sh
if_kue_load="YES"
```

## 描述

`kue` 驱动为基于 Kawasaki LSI KL5KLUSB101B 芯片组的 USB 以太网适配器提供支持。

KL5KLUSB101B 支持 128 条目多播过滤器、用于站地址的单个完美过滤条目和混杂模式。数据包通过单独的 USB 批量传输端点接收和发送。

Kawasaki 芯片组仅支持 10Mbps 半双工模式，因此没有可选的 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

`kue` 驱动支持基于 Kawasaki LSI KL5KLUSB101B 的 USB 以太网适配器，包括：

* 3Com 3c19250
* 3Com 3c460 HomeConnect Ethernet USB Adapter
* ADS Technologies USB-10BT
* AOX USB101
* ATen UC10T
* Abocom URE 450
* Corega USB-T
* D-Link DSB-650C
* Entrega NET-USB-E45, NET-HUB-3U1E
* I/O Data USB ETT
* Kawasaki DU-H3E
* LinkSys USB10T
* Netgear EA101
* Peracom USB Ethernet Adapter
* Psion Gold Port USB Ethernet adapter
* SMC 2102USB, 2104USB

## 诊断

* kue%d: watchdog timeout 数据包已排队等待传输并发出传输命令，但设备未能在超时到期前确认传输。
* kue%d: no memory for rx list 驱动无法为接收环分配 mbuf。

## 参见

arp(4), netintro(4), ng\_ether(4), [ifconfig(8)](/man/man8/ifconfig.8.md)

## 历史

`kue` 设备驱动最早出现于 FreeBSD 4.0。

## 作者

`kue` 驱动由 Bill Paul <wpaul@ee.columbia.edu> 编写。

## 缺陷

`kue` 驱动不会累计以太网冲突统计信息，因为 Kawasaki 固件似乎不维护任何内部统计信息。

# 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/kue.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.
