The patch filters out bridge devices.

NACK. It should list bridge devices. What shouldn't be listed is
*transient* interfaces (such as the bridge devices created by libvirt).
This is a problem inherent in the design of the udev driver. It's
examining the current state of the network system, while the original
intent of libvirt's interface driver was really to examine/modify the
persistent system config.
Get it, if so, netcf does a right work.
Thanks for this explanation.
I pointed this out to Doug at the time he
added the udev driver, and he acknowledged the problem but couldn't
think of a simple way to eliminate it, and it didn't seem serious enough
to delay adding in the driver.
