Bug 1291906

When you plug into the dock, what does 'dmesg' say?

What is the output of 'ip link' before and after you plug in?

How about 'ethtool <eth ifname>' before and after?

Googling around seems to indicate that the dock's ethernet is actually a separate USB ethernet device, so I would expect to see 3 network interfaces.  NetworkManager can't do much for the 3rd one if the kernel doesn't recognize it (since it's invisible to NM too).

The docking station (OneLink Pro) seems to use RTL8153 chipset, working with r8152 linux driver. But there are recent fixes to the driver:

https://lkml.org/lkml/2015/12/7/807
https://lkml.org/lkml/2015/9/6/226

So I would try several kernels, or even try compiling driver from RealTek:

And it seems that the hardware is [bleep]:

Hello Dan! Here is the dmesg from the docking station getting attached.

Here is ethtool before and after:

Jirka, I may attempt another kernel soon when I get some time to figure out how to do that with F23. I've also been considering upgrading this laptop to Rawhide, which may make testing that easier if I decide to go that route.

Ok, so the kernel does see the new ethernet device: enp0s20u3u1u3.  Can you:

1) start un-docked
2) run 'nmcli g log level debug'
3) verify no enp0s20u3u1u3 exists
4) dock the laptop
5) wait about 15 seconds or so
6) grab 'journalctl -b -u NetworkManager' and attach the output from before the dock (using the timestamps to snip it, perhaps)

Hi,

in the logs I see that the device is recognized by NM but a new
default connection is not created. This probably is already fixed in
recent NM versions by commit:

http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?h=nm-1-0&id=80d4fbf4ace3d8ed4428e17b0920ec32bdaf4fe1

which is available on master and in 1.0.8. Randy, can you please try
to upgrade NM to the 1.0.8 package from Fedora updates-testing repository
and see if it solves the problem?

Hello Beniamino,

Thanks so much for pointing me to that update, as it does resolve this issue. I don't see how I can link this issue to the bodhi update, but I'm happy to mark it as resolved by NetworkManager-1.0.8-1.fc23.x86_64:
