1.BMC虚拟多网口：macvlan是kernel提供的一种网卡虚拟化技术，可将网卡（不一定是真实的物理网卡）虚拟出多个接口，这网卡称为master或父接口，这些虚拟接口和外面环境通信都是通过父接口
1.1 bridge：ip netns add ns001 / ns002
macvlan模拟的mac不同，如下第一行和第二行创建两个以ens32为父接口的macvlan1和macvlan2虚拟网口。
如下将ns绑定网卡，进入ns001虚拟环境，将网卡up起来。
如下添加ip，不通原因是bridge模式和父接口（.138）是不通的。
宿主机（.1）指的windows这台机器，如下两个都是往外ping。
1.2 private：FB Openbmc（AST2520实物芯片）和OcpOpenBMC（qemu ast2500-evb）以及X86 Ubuntu上验证过， Kernel版本均5.0+
编译Kernel
BMC/CPU OS的Linux Kernel Config里面加CONFIG_MACVLAN=m/y，如下是BMC：
如下在编译的服务器上编译完后，如果找不到就删除build目录重新编译。
如下在烧录的机器上烧录镜像后，vi第一行.dep文件。
如下不用insmod kernel/drivers/net/maclan.ko。
创建/启动网卡/获取DHCP地址
创建网卡以eth0为目标物理网口，虚拟网口的MAC地址自定义，这里mode可以选择private不能互通，bridge内部互通等。假设生成5个虚拟网口eth0.1-eth0.5，命令如下，ifconfig检查5个虚拟网口的IP地址和MAC地址（都不一样）：
ip link add link eth0 dev eth0.1 address D6:D2:52:A8:28:28 type macvlan mode private
ip link add link eth0 dev eth0.2 address D6:D2:52:A8:28:29 type macvlan mode private
ip link add link eth0 dev eth0.3 address D6:D2:52:A8:28:2a type macvlan mode private
ip link add link eth0 dev eth0.4 address D6:D2:52:A8:28:2b type macvlan mode private
ip link add link eth0 dev eth0.5 address D6:D2:52:A8:28:2c type macvlan mode private
ifconfig eth0.1 up
ifconfig eth0.2 up
ifconfig eth0.3 up
ifconfig eth0.4 up
ifconfig eth0.5 up
dhclient eth0.1
dhclient eth0.2
dhclient eth0.3
dhclient eth0.4
dhclient eth0.5
配置路由表
配置路由表的目的：由于5个网口都被分配在一个网段如10.75.159.0/24（掩码一样），导致Linux 内部路由会以高优先级的网口如eth0来响应外部的arp/icmp/tcp等各种网络请求。为了达到5个虚拟网口能在同网段以5个独立网口的形式工作，呈现5个独立网口MAC地址，需要配置路由表。获取Gateway网关地址：用route -n 命令获取路由表和Gateway（10.75.159.1）地址。
配置路由表：数量以实际虚拟网卡数量为准，需要替换网关IP和每个网口的IP。下面命令中10.75.159.1为网关地址，10.75.159.117等为虚拟网口的IP地址，10.75.159.0/24为网段和NETMASK。
echo "210 eth0table" >> /etc/iproute2/rt_tables 210越大优先级越低
echo "220 eth1table" >> /etc/iproute2/rt_tables
echo "230 eth2table" >> /etc/iproute2/rt_tables
echo "240 eth3table" >> /etc/iproute2/rt_tables
echo "250 eth4table" >> /etc/iproute2/rt_tables
ip route add 10.75.159.0/24 dev eth0.1 src 10.75.159.117 table eth0table
ip route add 10.75.159.0/24 dev eth0.2 src 10.75.159.120 table eth1table
ip route add 10.75.159.0/24 dev eth0.3 src 10.75.159.121 table eth2table
ip route add 10.75.159.0/24 dev eth0.4 src 10.75.159.125 table eth3table
ip route add 10.75.159.0/24 dev eth0.5 src 10.75.159.132 table eth4table
ip route add default dev eth0.1 via 10.75.159.1 table eth0table
ip route add default dev eth0.2 via 10.75.159.1 table eth1table
ip route add default dev eth0.3 via 10.75.159.1 table eth2table
ip route add default dev eth0.4 via 10.75.159.1 table eth3table
ip route add default dev eth0.5 via 10.75.159.1 table eth4table
ip rule add from 10.75.159.117 table eth0table
ip rule add from 10.75.159.120 table eth1table
ip rule add from 10.75.159.121 table eth2table
ip rule add from 10.75.159.125 table eth3table
ip rule add from 10.75.159.132 table eth4table
远端服务器检查
远端服务器发起ping：通过发起ping，获取相应网口的MAC地址信息。
ping 10.75.159.117
ping 10.75.159.120
ping 10.75.159.121
ping 10.75.159.125
ping 10.75.159.132
如下远端服务器arp -a，可看到BMC侧IP的MAC地址与远端服务器获取的一致，符合预期。
使用tcp方式测试，BMC端 iperf -s -p port
测试服务器端 iperf -c BMCIP -t 1000 -i 3 -p port
