流程

1. 创建一个 playbook 文件，如 ~/configure-ethernet-device-with-ethtoolcoalesce-settings.yml，其内容如下：

   ---
   - name: Configure the network
     hosts: managed-node-01.example.com
     tasks:
     - name: Configure an Ethernet connection with ethtool coalesce settings
       include_role:
         name: rhel-system-roles.network
   
       vars:
         network_connections:
           - name: enp1s0
             type: ethernet
             autoconnect: yes
             ip:
               address:
                 - 198.51.100.20/24
                 - 2001:db8:1::1/64
               gateway4: 198.51.100.254
               gateway6: 2001:db8:1::fffe
               dns:
                 - 198.51.100.200
                 - 2001:db8:1::ffbb
               dns_search:
                 - example.com
             ethtool:
               coalesce:
                 rx_frames: 128
                 tx_frames: 128
             state: up
