我用yocto项目为Banana Pro板构建了一个图像。我正在尝试通过连接端口，ssh [email protected]但不能。
Ssh总是挂在Entering interactive session舞台上。当我运行ssh -v参数时，我捕获了以下日志：

我试图更改MTU，但没有成功。
我怎么解决这个问题？
问题完全是偶然解决的，我也不知道为什么。
通常，在连接了以太网电缆的情况下启动后，我一直在手动运行modprobe sunxi-gmac和/etc/init.d/networking restart命令。但是这次，偶然地，我忘记了预先插入电缆，而是在/etc/init.d/networking restart命令运行期间将其插入（发送发现阶段）。令我惊讶的是，已经实现了ssh连接！此行为是确定性的（已尝试）。
谁能解释这个奇怪的情况？为什么在网络重新启动时而不是在此之前插入以太网电缆？
