1.查看网口IP（本次以usb0为例）

  root@localhost:~# ip link
  1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
      link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
  2: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN mode DEFAULT group default qlen 1000
      link/sit 0.0.0.0 brd 0.0.0.0
  3: usb0: <NOARP,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
      link/ether 02:50:f4:00:00:00 brd ff:ff:ff:ff:ff:ff
  4: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
      link/ether 0e:55:3a:cc:05:be brd ff:ff:ff:ff:ff:ff
  5: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq master br0 state DOWN mode DEFAULT group default qlen 1000
      link/ether 3a:63:01:e2:10:b5 brd ff:ff:ff:ff:ff:ff
  6: br0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000
      link/ether 06:e5:0a:f4:cb:44 brd ff:ff:ff:ff:ff:ff
  7: lxcbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000
      link/ether 00:16:3e:00:00:00 brd ff:ff:ff:ff:ff:ff
  8: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000
      link/ether 52:54:00:ef:a1:22 brd ff:ff:ff:ff:ff:ff
  9: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast master virbr0 state DOWN mode DEFAULT group default qlen 1000
      link/ether 52:54:00:ef:a1:22 brd ff:ff:ff:ff:ff:ff

可以看到usb0网口的MAC为：02:50:f4:00:00:00

2.创建文件夹/etc/udev/rules.d/70-persistent-net.rules

  
  vim /etc/udev/rules.d/70-persistent-net.rules
  文件内容：
  # Realtek 8211CU Wifi AC 0bda:c811
  SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="02:50:f4:00:00:00", NAME="wlan1"

3.重新启动板卡查看效果

  root@localhost:~# ifconfig
