android4.0.4 增加ethernet

這個是對android4.0.3增加ethernet我是直接拿過來對android4.0.4增加，過程中有些是不同的，錯誤比較容易解決這裡我就不作具體說明了。只是其中有一點需要修改的在這個地方： 2. system\core\libnetutils\dhcp_utils.c的 dhcp_do_request函數中，把 snprintf(daemon_cmd,sizeof(daemon_cmd),"%s","dhcpcd_wlan0");改成 snprintf(daemon_cmd,sizeof(daemon_cmd),"%s","dhcpcd_eth0"); 要是改成這樣無線網絡就用不了，所以我稍微改了下 [java]       /* 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);   把原來的注釋掉，然後改成上面那樣。 同時在init.rc中加上這個服務: [html]   service dhcpcd_eth0 /system/bin/dhcpcd -o domain_name_servers -dd -ABKL eth0       class main       disabled       oneshot   現在有線和無線就都能正常連接了。
