Public bug reported:

Currently, when lb agent needs to check if an interface exists on a
bridge, it will get all interfaces on the bridge and looks for the
interface:

 for filename in os.listdir(BRIDGE_INTERFACES_FS):
   if filename == interface:
     return True
   return False

when we can directly check os.path.join(BRIDGE_INTERFACE_FS, interface)
existence.
