# oce.4

`oce` — Emulex OneConnect 10Gb 网络适配器设备驱动

## 名称

`oce`

## 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 pci device oce

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

```sh

## 描述

Emulex OneConnect 适配器有各种型号，具有不同的 NIC、FCoE 和 iSCSI 功能组合。`oce` 驱动声明所有这些适配器中的 NIC 功能。

`oce` 驱动支持 VLAN 硬件卸载、TCP 校验和卸载、TCP 分段卸载（TSO）、大接收卸载（LRO）、Bonding、巨帧（从 1500 到 9000）、多 TX 队列、接收端缩放（RSS）和 MSI-X 中断。

## 硬件

`oce` 驱动支持以下网络适配器：

* Emulex BladeEngine 2
* Emulex BladeEngine 3
* Emulex Lancer

## 固件更新

适配器固件更新是持久性的。

可按以下步骤更新固件：

```sh
KMOD=elxflash
FIRMWS=imagename.ufi:elxflash
.include <bsd.kmod.mk>
```

* 将以下代码复制到 Makefile：
* 将上面的 imagename 替换为 UFI 文件名
* 将 Makefile 和 UFI 文件复制到某个目录
* 执行 make 并将生成的 elxflash.ko 复制到 `/lib/modules`
* sysctl dev.oce.\<if\_id>.fw\_upgrade=elxflash
* 重启机器

如果提供的 UFI 有问题，刷写会失败并出现以下错误之一。

* "Invalid BE3 firmware image"
* "Invalid Cookie. Firmware image corrupted ?"
* "cmd to write to flash rom failed."

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/oce.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.
