This is information I could look up, but would take time, so let's see if you 
already have the answers 😉 Does this fail 100% of the time now, and since when? 
Or when did it become flaky? We noticed on our servers, that when we moved the 
VMs to run on different physical machines in different facilities, the ETH0 
became ETH1, despite being the same VM. They are still in the same vsphere and 
all, but for some reason that changed. It could be that this happened to the 
VMs running the builds and tests as well, but I would imagine this happening 
then 100% of the time, and everything would have been blocked since we moved. 
And that we would have noticed here. Odd..

Emergency workaround: https://codereview.qt-project.org/197753
(compiles and works for me on bare metal, no test on a VM)

This commit basically disables the test entirely on virtual machines. If any 
QtNetwork developers use virtual machines, please make sure you get bare-metal 
hardware for all three platforms. You won't be doing your job if you continue 
with VMs.
