+# lwip 移植说明
+
+为了适配 RT-Thread 网卡设备，RT-Thread 团队基于原 [lwip](http://savannah.nongnu.org/projects/lwip/) 进行了一些修改，本文档记录了相关修改内容。
+
+> 本 lwip-2.1.2 版本基于 [lwip STABLE-2_1_2_RELEASE](https://git.savannah.gnu.org/git/lwip.git) 版本移植而来。

+| :---- | :---- | :---- |
+| 2019-09-02 | MurphyZhao | 增加 lwip 2.1.2 移植说明 |
+| 2020-06-18 | xiangxistu | 增加部分 lwIP 2.1.2 移植说明 |
+
+## 修改内容
+
+### src/api
+
+- `src/api/sockets.c` 增加 `lwip_tryget_socket` 函数，作为 `tryget_socket` 函数的全局实现
+- `src/api/sockets.c` 在 `alloc_socket` 函数中，增加 SAL 移植函数 `rt_wqueue_init`
+
+```
+#ifdef SAL_USING_POSIX
+      rt_wqueue_init(&sockets[i].wait_head);
+#endif
+```
+
+### src/app
+
+- 增加 `ping/ping.c`，便于在 finsh/msh 中使用 ping 功能
+- 增加 `tftp/tftp_port.c`，便于在 finsh/msh 中使用 tftp_server 功能
+
+### src/arch
+
+增加 `src/arch` 目录，存储对接 RT-Thread 设备框架的移植文件，从 lwip-2.0.2 版本中的移植文件修改而来。
+
+
+
+以及相对于 lwIP2.0.2 的增加修改内容：
+
+
+* 在 `src/arch/sys_arch.c` 中增加 MTU 与 etharp_output 的初始化
+
+* 在 `src/arch/sys_arch.c` 中增加新添加的邮箱函数
+
+  对邮箱机制的新增加的 sys_mbox_trypost_fromisr 函数予以实现
+
+* 在 `src/arch/sys_arch.c` 中增加新添加的内存堆函数
+
+  对内存堆的新增加的 mem_overflow_check_raw 与 mem_overflow_init_raw 函数予以实现
+  
+* 在 `src/arch/cc.h` 中增加对 lwIP 使用的标准错误代码宏的处理，不再使用 lwIP 内置的错误宏
+
+
+### src/core
+
+- 在 `src/core/dns.c` 的 `dns_setserver` 函数中增加 RT-Thread netdev 相关的移植
+- 在 `src/core/netif.c` 中增加 RT-Thread netdev 相关的移植
+
+### src/include
+
+- 在 `src/include/lwip/priv/sockets_priv.h` 中增加 SAL 相关的移植
+
+    在 `lwip_sock` 结构体中增加 `  rt_wqueue_t wait_head;` 成员
+
+- 在 `src/include/lwip/prot/ieee.h` 中增加 EAPOL, EAP over LAN 标识
+
+- 在 `src/include/lwip/init.h` 中的版本号后增加 `U` 标识
+
+- 在 `src/include/lwip/sockets.h` 中增加 `LWIP_SOCKET_SELECT`，解决开启 RT_USING_POSIX 时的冲突
+
+- 在 `src/include/lwip/arch.h` 中修改 `<unistd.h> `为 `"sys/types.h" `，解决编译冲突
+
+    并添加 typedef int ssize_t 定义，补足因 libc 与 dfs 未开启时 ssize_t 的定义不足问题
+
+- 在 `src/include/netif/` 中增加 `ethernetif.h`，用于对接 RT-Thread 网卡设备
+
+### src/netif
+
+- 在 `src/netif/` 中增加 `ethernetif.c`，用于对接 RT-Thread 网卡设备
+- 在 `src/netif/lowpan6.c` 中增加 `LWIP_6LOWPAN` 宏定义，以防止编译错误
+
+### src
+
+- 在 src 目录下，增加 `src/lwipopts.h`，用于 lwip 功能裁剪以及配置设置
+- 在 src 目录下，增加 `src/lwippools.h`，用于定义 `LWIP_MALLOC_MEMPOOL`
