** Description changed:

+ [Impact]
+ 
+ Booting this image:
+ 
+ http://cdimage.ubuntu.com/releases/18.04/beta/ubuntu-18.04-beta-
+ preinstalled-server-arm64+raspi3.img.xz
+ 
+ on a RaspberryPi 3B+, the ethernet port is not working.
+ 
+ Moving the EEE enabling into the PHY initialisation function,
+ immediately after the connection to the PHY is established, which is
+ long before phy_start is called, prevents the renegotiation and avoids
+ the slowdown and failure.
+ 
+ [Fix]
+ 
+ Apply the attached patch and recompile
+ 
+ [Test]
+ 
+ Install a patched kernel and reboot, if the image boots and eth0 is
+ working, the fix is working
+ 
+ [Regression]
+ 
+ The patch is already in Cosmic and it fixes an isolated bug, so i say
+ it's low

  I'm trying a new image with kernel 4.15.0-1029.31 and ethernet works
  fine on my older rpi3 (v1.2) but with the b+ it doesn't seem to be
  working. Lower right LED is blinking, lower left is off.
  
  I'll try to get some output via serial, no other way to connect to it at
  the moment
