700+mW for nic:virbr0?
by Chris Murphy
The #2 power consumer on my laptop according to powertop is
nic:virbr0 which seems unlikely. That's more than Firefox, and a bit
less than the display backlight. And it's nearly 300x more power than
used by the wifi driver.

862 mW 0.0 pkts/s Device nic:virbr0
If it's wrong, it's a powertop bug. If it's real, then it's a bug
somewhere maybe in libvirt or maybe the kernel? There has been no VM
running during this boot, so nic:virbr0 shouldn't even be in use.
Is this the actual wifi radio, but somehow virb0 is just getting dinged?
