salt-minion:
    ----------
    sysctl:
        
        Configuration of the Linux kernel using sysctl
        ==============================================
        
        Control the kernel sysctl system.
        
          vm.swappiness:
            sysctl.present:
              - value: 20
    sysctl.present:
        
            Ensure that the named sysctl value is set in memory and persisted to the
            named configuration file. The default sysctl configuration file is
            /etc/sysctl.conf
        
            name
                The name of the sysctl value to edit
        
            value
                The sysctl value to apply
        
            config
                The location of the sysctl configuration file. If not specified, the
                proper location will be detected based on platform.

ES:
net.ipv4.ip_forward:
  - name: net.ipv4.ip_forward
  - value: 0
net.ipv4.tcp_syn_retries:
  - name: net.ipv4.tcp_syn_retries
  - value: 1
net.ipv4.tcp_tw_recycle:
  - name: net.ipv4.tcp_tw_recycle
  - value: 1
net.ipv4.tcp_tw_reuse:
  - name: net.ipv4.tcp_tw_reuse
  - value: 1

备注：个人不觉得使用 sysctl module 到底好在哪里， 也可以使用，sysctl.conf文件，直接 file到 node， 通过 sysctl -p 一样可以实现。
