I am using the Yocto project to build my kernel/distro for my VMs, since 
that is what we use on our hardware.  Here is the output from those 
commands:

root@sierra1:~# ip link show dev bat0
6: bat0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state 
UNKNOWN mode DEFAULT group default
     link/ether f2:52:c3:50:2e:d7 brd ff:ff:ff:ff:ff:ff

root@sierra1:~# uname -a
Linux sierra1 4.1.18-rt15-yocto-preempt-rt #1 SMP PREEMPT RT Wed May 4 
23:15:13 MDT 2016 x86_64 GNU/Linux

My guess, per Matthias next email in the thread, is that IPv6 is 
required, which I believe is not built into my kernel.  I'll see about 
adding that and try again.

Thanks!
Jon
