Help with fc20 NIC power?

[William Murray]

   Hi all,
         F20 installed, all seems nice - except the power. I am using 
'powertop' which reports 19W
on virbr and 13 on wlp3s0. A full battery last 40mins, c/f 4 hrs on FC19.
My interfaces look like this:

I set up the virbr for my VM's - those are currently all off.  I may have
messed up the config, but it was working nicely in F19.
If I switch off the wireless the virbr still uses O(20W). Any ideas
how to debug? I cannot even see config files. Help my laptop battery 
dies NOW.
    Thanks!!
      Bill
