# FXMAC 驱动程序
|
|||
|
|
|
|||
|
|
## 1. 概述
|
|||
|
|
|
|||
|
|
以太网控制器（XMAC）的主要功能是在兼容 IEEE802.3 standard 标准的以太网中发送和接收数据，当前支持 SGMII/RGMII 的 PHY 接口
|
|||
|
|
|
|||
|
|
XMAC 接口特点包括
|
|||
|
|
- 支持速率 1000Mbps/100Mbps/10Mbps
|
|||
|
|
- 支持 Reduced Gigabit Media Independent Interface (RGMII)
|
|||
|
|
- 支持 SGMII Serial Gigabit Media-Independent Interface （SGMII）
|
|||
|
|
|
|||
|
|
## 2. 功能
|
|||
|
|
|
|||
|
|
XMAC 驱动提供了以太网控制器的初始化，DMA 环形队列使用函数，外部PHY 接口相关的配置功能
|
|||
|
|
|
|||
|
|
XMAC 驱动程序的源文件包括，
