把OTG配上USB网卡功能，PC机重启时USB网卡不能正常使用

hapbir

我参考wiki教程[https://wiki.t-firefly.com/Core-3328-JD4/ubuntu_manual.html#usb-yi-tai-wang]，在OTG口开启USB网卡功能。
1> PC（CentO S7.9、Ubuntu18.04）已开机，初次连接USB线到OTG口；
或
2> 接着USB线重启PC;
在PC上枚举的网卡名不太一样，如enp0s29f7u6c2i1，这样的网卡名即使配置IP也不能用。
重新插拔USB线或在板子上重新加载那些驱动文件后正常，PC上的网卡名变为enp0s29f7u6c2，配置IP后可用。

请问一下这是哪儿的问题，是我配错了么？

自己回答一下吧。
找了一些资料说是Linux对TNDIS支持不太好（具体情况不太了解）。把“RNDIS support (NEW)”取消，在Linux系统上试倒是正常了。
