e1000e regression - 5.4rc1

[Tobias Klausmann]

Hello all,

While testing the 5.4rc1 release, i noticed my Ethernet never coming 
fully up, seemingly having a timeout problem. While bisecting this i 
landed at the commit dee23594d587386e9fda76732aa5f5a487709510 ("e1000e: 
Make speed detection on hotplugging cable more reliable") as the first 
bad commit. And indeed just reverting the commit on top of 5.4rc1 
resolves the problem. Let me know if you have further questions, or 
patches to test!

Greetings,

Tobias
