嵌入式linux实现pppoe拨号上网

make menuconfig -> Device Drivers -> Network device support -> PPP (point-to-point protocol) 中，选中所有ppp选项。退出，保存配置，修改Makefile重新执行make zImage. 将arch/mips/boot/下的zImage下载到开发板上重启系统。

tar -zxvf ppp-2.4.5.tar.gz
cd ppp-2.4.5

[root@root ppp-2.4.5 ]# ./configure CC=mipsel-linux-gcc AR=mipsel-linux-ar BANLIB=mipsel-linux-ranlib --host=mipsel
