# ccr.4
`ccr` — Chelsio T6 加密加速器驱动
## 名称
`ccr`
## 概要
要将此驱动编译进内核，请将以下行放入内核配置文件中：
> device ccr device cxgbe
要在引导时以模块形式加载该驱动，请在 [loader.conf(5)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man5/loader.conf.5.md) 中加入以下行：
```sh
ccr_load="YES"
```
## 描述
`ccr` 驱动为基于 Chelsio Terminator 6 ASIC（T6）的 PCI Express 以太网适配器上集成的加密加速引擎提供支持。该驱动为 [crypto(9)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man9/crypto.9.md) 消费者（如 [ktls(4)](/man/man4/ktls.4.md)、geli(4) 和 [ipsec(4)](/man/man4/ipsec.4.md)）加速 AES-CBC、AES-CCM、AES-CTR、AES-GCM、AES-XTS、SHA1、SHA2-224、SHA2-256、SHA2-384、SHA2-512、SHA1-HMAC、SHA2-224-HMAC、SHA2-256-HMAC、SHA2-384-HMAC 和 SHA2-512-HMAC 操作。该驱动还支持将 AES-CBC、AES-CTR 或 AES-XTS 之一与 SHA1-HMAC、SHA2-224-HMAC、SHA2-256-HMAC、SHA2-384-HMAC 或 SHA2-512-HMAC 之一链接，用于先加密后认证操作。有关进一步的硬件信息和与硬件要求相关的问题，请参见 。
`ccr` 驱动作为现有 Chelsio NIC 设备的子设备附加，因此需要 [cxgbe(4)](/man/man4/cxgbe.4.md) 驱动处于活动状态。
## 硬件
`ccr` 驱动支持基于 T6 ASIC 的适配器上集成的加密加速引擎：
* Chelsio T6225-CR
* Chelsio T6225-SO-CR
* Chelsio T62100-LP-CR
* Chelsio T62100-SO-CR
* Chelsio T62100-CR
## 支持
有关一般信息和支持，请访问 Chelsio 支持网站：
如果在使用所支持适配器时发现此驱动存在问题，请将与问题相关的所有具体信息通过电子邮件发送至 。

## 历史
`ccr` 设备驱动首次出现于 FreeBSD 12.0。
## 作者
`ccr` 驱动由 John Baldwin 编写。

## 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/ccr.4.md?ask=&goal=
```
`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.
