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路就用不了，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串連了。
