大家好、团队成员：
我想 在 MAC 模式下使用 CPSW2G 内核 直接连接到另一台计算机。
测试环境：
| 位置 | J721EXCP01EVM www.ti.com/.../J721EXCP01EVM |
| 示例 | Jacinto-J7200—适用于 PROCESSOR-SDK-LINUX 处理器的 Linux SDK SDK 版本：10.00.07.03 (https://www.ti.com/tool/PROCESSOR-SDK-J7200) |
| 引导模式 | SD 卡 |
| 内核版本 | 6.6.32-ti |
但是、在之前的 SDK 版本09.02.00.04中、CPSW2G 运行良好并可以成功 ping 通 DUT。
在 SDK 版本10.00.07.03中、CPSW2G 为 不会 非常实用 1g. 速度设置。
