I have a new Lenovo Thinkpad T550 and am using Debian Testing on it.
$ uname
SMP Debian 4.4.6-1 (2016-03-17) x86_64

In dmesg I see:
dmesg | grep eth0
[ 0.668204] e1000e 0000:00:19.0 eth0: registered PHC clock
[ 0.668206] e1000e 0000:00:19.0 eth0: (PCI Express:2.5GT/s:Width x1) 54:ee:75:8f:16:cc

[ 0.668629] e1000e 0000:00:19.0 enp0s25: renamed from eth0
Why would this be? I have never seen it before on Debian Linux of which I am a user since 1995.
