Embeded linux之网卡驱动

一、配置菜单

Device Drivers

[*] Network device support  --->

网络设备驱动、网卡驱动

< >     Bonding driver support  

功能：多网卡绑定

具体操作为：将多个以太网通道绑定为一个,也就是两块网卡具有相同的IP地址并且聚合成一个逻辑链路工作,可以用来实现负载均衡或硬件冗余

< >     Dummy net driver support

功能：哑接口网络

使用环境：使用SLIP或PPP传输协议(如ADSL用户)的需要它

具体操作：设置一个虚拟网络。虚拟网络(dummy network)就像网络中的/dev/null。任何发送给虚拟网络的数据都会永久消失，因为它会发往/dev/null。IP地址没有设置。用户可以定义他们的网络相当于/dev/null）

< >     EQL (serial line load balancing) support

功能：串行线路的负载均衡

具体操作：如果有两个MODEM和两条电话线而且用SLIP或PPP协议,该选项可以让您同时使用这两个MODEM以达到双倍速度(在网络的另一端也要有同样的设备)

< >     Generic Media Independent Interface device support 

功能：通用媒体独立接口设备支持

背景介绍：MII是一种用于最高速度为100Mbit/s以太网的接口。以太网线缆用于连接到PHY ceiver，是一种以太网收发器

< >     Ethernet team driver support (EXPERIMENTAL)  --->

功能：team网卡组支持

背景介绍：通过虚拟接口组织许多以太网设备

< >     MAC-VLAN support (EXPERIMENTAL) 

功能：允许用户在特定的MAC地址和某个接口上映射数据包

具体操作：基于MAC地址的VLAN，一种根据报文的源MAC地址来确定untagged报文所属VLAN的划分方法

< >     Network console logging support

网络远程命令支持，远程登录用

注意：内核发送给网络的消息可任意通过这个特性记录下来。除非记录网络信息对你很重要时才启用它。禁用这个特性会增强性能。

< >     Universal TUN/TAP device driver support

TUN/TAP可以为用户空间提供包的接收和发送服务,比如可以用来虚拟一张网卡或点对点通道

使用环境：如果用户空间程序希望使用TAP设备

< >     Virtual ethernet pair device

本地以太网隧道

<*>   PHY Device support and infrastructure  --->

数据链路层芯片简称为MAC控制器,物理层芯片简称之为PHY,通常的网卡把MAC和PHY的功能做到了一颗芯片中,但也有一些仅含PHY的"软网卡"，这里就是软网卡的驱动

< >   Micrel KS8995MA 5-ports 10/100 managed Ethernet switch

5端口10/100M以太网交换机芯片KS8995MA

< >   PPP (point-to-point protocol) support

点对点协议,PPP已经基本取代SLIP了,ADSL拨号上网方式

< >   SLIP (serial line) support

一个在串行线上(例如电话线)传输IP数据报的TCP/IP协议.

驱动支持SLIP和CSLIP。SLIP(Serial Line Internet Protocol)是一种用于调制解调器和串口的因特网驱动。PPP现在用来代替SLIP。CSLIP是压缩的SLIP。

二、对应的Kconfig

driver/net/Kconfig

source "drivers/net/ethernet/Kconfig"

driver/net/ethernet/Kconfig

menuconfig ETHERNET
bool "Ethernet driver support"
depends on NET
default y
---help---
This section contains all the Ethernet device drivers.

if ETHERNET

source "drivers/net/ethernet/hieth-gmac/Kconfig"

endif 

drivers/net/ethernet/hieth-gmac/Kconfig

menuconfig HIETH_GMAC
tristate "hieth gmac family network device support"
depends on ARCH_HI3516A
default y
help
This selects the hieth gmac family network device. The gigabit
switch fabric (GSF) receives and transmits data over two Ethernet
ports at 10/100/1000 Mbit/s in full-duplex or half-duplex mode.
The Ethernet port exchanges data with the CPU port, and supports
the energy efficient Ethernet (EEE) and wake on LAN (WoL) functions.

if HIETH_GMAC
