[lfs-support] "Interesting" Names

With all the interest in helping Alan to get his ethernet card working, 
one of the things that caught my attention was the name that appeared 
for him in "/sys/class/net."  I googled "enp3s0" and saw many, many 
threads in different lists and fora about exactly the same situation.  
People couldn't get their "eth0" working and were surprised to find out 
that it wasn't "eth0" any more but something else.

There were many allusions to the "new naming convention."  enpxx for 
ethernet and wlpxx for wireless.  Where does this name convention 
exist?  I remember that xlnglp posted about what he had discovered in 
the "different" names, but I can't find what he wrote.  I don't remember 
if he had identified a source.

I'd like to be prepared for future efforts so that I don't bark up 
incorrect trees.

Here's the mystery for me:  Alan and I have the same NIC.  We probably 
have different boxes, but I don't think that's relevant. He built 
LFS-7.4 just like I did.  Kernel 3.10.10 + identical NIC = same kernel 
configuration.  However, his NIC is named "enp3s0" in /sys/class/net and 
mine is named "eth0" in /sys/class/net.  Why the difference?  Where did 
the difference originate?  What is its source?

More googling.  But first--UEFI.
