XILINX官方默認的lwip bsp驅動暫時不支持RTL8211網口芯片，在使用該網口的時候需要自己手動修改庫文件以支持該芯片,不同版本工具之間的修改方式大同小異，這邊僅以Vitis 2019.2爲例。
PS端網口以米聯客MZU07A board爲例：
Step1：首先，找到vitis ide安裝目錄下的LWIP庫的路徑，將其拷貝一份放到工程目錄下：
Step2：修改lwip211_v1_1\data\lwip211.mld文件（可用Notapad++等編輯器打開），將其中的版本編號
OPTION VERSION =1.1;
修改爲
OPTION VERSION = 1.2;;
Step3：打開lwip141_v2_0\src\contrib\ports\xilinx\netif\ xemacpsif_physpeed.c，進行如下修改
根據芯片手冊定義Realtek PHY芯片的ID
| #define PHY_REALTEK_IDENTIFIER 0x001c |
Step4：在get_Marvell_phy_speed庫函數基礎上，對rtl8211的特殊狀態寄存器進行修改，然後保存

return XST_SUCCESS; } |

return XST_SUCCESS; } |
Step5：在vitis軟件中導入修改後的lwip庫的路徑（需根據實際情況更改此路徑，若不更改將產生錯誤）
Step6：導入庫文件後重啓SDK
Step7: 勾選lwip庫文件
Step8: 選擇lwip211_1.2版本
Step9: 選擇File->New->Application Project->lwip_echo_server
Step10:右擊lwip_testàDebug Asà Debug Configurations,然後單擊debug
Step11:單擊運行，查看輸出結果
PL端網口以米聯客MA703_100T爲例
Xilinx SDK 目錄下面 xaxiemacif_physpeed.c 文件裏面對 PHY 芯片有驅動，目前支持 MARVEL 和 TI 的部分 PHY 芯片，如果使用其他廠家的 PHY 芯片，需要更改驅動，否則協商不能通過。
打開fpga_prj\uisrc\07_sdk_src\lwip211_v1_1\src\contrib\ports\xilinx\netif\xaxiemacif_physpeed.c 源文件，增加宏定義
添加PHY ID的定義
