Hi Joe!

Those tools (along with arp and route) have long been deprecated and 
should be substituted with their modern equivalents from the iproute2 

       * arp -> ip [-r] neigh
       * ifconfig -> ip a
       * netstat -> ss [-r]
       * route -> ip r

If you really, really, really want to continue to use the old 
unsupported tools I think SLE 15 has the 'net-tools-deprecated' package 
which will install them, but the package description gives the same 
recommendation as above.

The new interface naming is not 'whimsical' but solves real problems. I 
for one quite like the fact that I now have stable device naming 
regardless of tinkering with VM configurations, adding/removing cards on 
real hardware, etc etc

A simple 'lspci' is all I need now to predictively create configuration 
required for a card, whereas with the previous model I could never be 
100% certain my scripted 'eth0' configurations would land on the CORRECT 
card on the system.

It's compatibility with a read-only root filesystem is also a boon for 
the work we're doing with CaaSP and Kubic. I'm quite sick of the bugs I 
have in Kubic right now because we haven't yet implemented this there as 
effectively as you see in the SLE-15 beta.

There's a lot more information about this on the Freedesktop.org site:
