光纤环网mstpd编译，移植到am335x
1、下载
git clone https://github.com/mstpd/mstpd
2、配置
sudo ./autogen.sh
3、配置
./configure --build=i686-linux --host=arm-arago-linux-gnueabi --target=arm-arago-linux-gnueabi --prefix=/home/picohood/projects/tools/ring_net/mstpd/install_lsh CC=arm-arago-linux-gnueabi-gcc CXX=arm-arago-linux-gnueabi-g++ --disable-udev
4、编译
make
目前只支持am335x本体的网卡
1、拷贝bridge-stp
cp bridge-stp /sbin/
cp mstpd /sbin
2、创建目录
mkdir /lib/mstpctl-utils
cp mstp_config_bridge ifupdown.sh ifquery mstpctl-utils-functions.sh /lib/mstpctl-utils
3、创建文件 /etc/network/bro.config
填写内容
address: 192.168.3.10
netmask: 255.255.255.0
gateway: 192.168.3.1
bridge_ports: eth0 eth1
重要注释
bridge-stp这个脚本很重要 在ifupdown.sh里会调用"$brctl" stp "$IFACE" on 该命令即是brctl stp br0 on，它是为了触发内核代码。执行判断是kernel_stp，还是user_stp；
如果在/sbin/里没有bridge-stp，应用层无论是用rstp还是mstp协议。都会强制使用内核的stp协议。
修改 /etc/network/interfaces
# bridge lsh

iface lo inet loopback
iface br0 inet static
address 192.168.3.10
netmask 255.255.255.0
