已经有人在这方面做了研究了请先看这篇博客：[点击打开链接][Link 1]

这个是对android4.0.3增加ethernet我是直接拿过来对android4.0.4增加，过程中有些是不同的，错误比较容易解决这里我就不作具体说明了。只是其中有一点需要修改的在这个地方：

2. system\\core\\libnetutils\\dhcp\_utils.c的 dhcp\_do\_request函数中，把

snprintf(daemon\_cmd,sizeof(daemon\_cmd),"%s","dhcpcd\_wlan0");改成

snprintf(daemon\_cmd,sizeof(daemon\_cmd),"%s","dhcpcd\_eth0");

要是改成这样无线网络就用不了，所以我稍微改了下

/* Erase any previous setting of the dhcp result property */
        property_set(result_prop_name, "");
    #if 0
        /* Start the daemon and wait until it's ready */
        if (property_get(HOSTNAME_PROP_NAME, prop_value, NULL) && (prop_value[0] != '\0'))
            snprintf(daemon_cmd, sizeof(daemon_cmd), "%s_%s:-h %s %s", DAEMON_NAME, daemon_suffix,
                     prop_value, interface);
        else
            snprintf(daemon_cmd, sizeof(daemon_cmd), "%s_%s:%s", DAEMON_NAME, daemon_suffix, interface);
    /// modfiy by dao  ///
        //snprintf(daemon_cmd,sizeof(daemon_cmd),"%s","dhcpcd_wlan0");
          snprintf(daemon_cmd,sizeof(daemon_cmd),"%s","dhcpcd_wlan0");
    //
    #else
    #if 1
        /* Start the daemon and wait until it's ready */
        if (property_get(HOSTNAME_PROP_NAME, prop_value, NULL) && (prop_value[0] != '\0'))
            //snprintf(daemon_cmd, sizeof(daemon_cmd), "%s:-h %s %s", DAEMON_NAME,
                    // prop_value, interface);
    	snprintf(daemon_cmd, sizeof(daemon_cmd), "%s_%s", DAEMON_NAME, interface);
        else
    #endif
            snprintf(daemon_cmd, sizeof(daemon_cmd), "%s_%s", DAEMON_NAME, interface);
    #endif
        memset(prop_value, '\0', PROPERTY_VALUE_MAX);

把原来的注释掉，然后改成上面那样。

同时在*init.rc中加上这个服务:*

service dhcpcd_eth0 /system/bin/dhcpcd -o domain_name_servers -dd -ABKL eth0
        class main
        disabled
        oneshot

现在有线和无线就都能正常连接了。
