有時候新增網路卡後，看系統預設的名稱會不知道哪一張網路卡是做什麼用的

又或者是網路卡會跳號，龜毛人如我看了就會不舒服

就像這樣：

$ ifconfig -a
enp0s3    Link encap:Ethernet  HWaddr 08:00:27:51:3c:5b
          inet addr:192.168.56.101  Bcast:192.168.56.255  Mask:255.255.255.0

          RX bytes:7787 (7.7 KB)  TX bytes:9395 (9.3 KB)

          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host

我們可以藉由 Linux udev 將網路卡名稱更改成自己喜歡的名稱
