Title:
  linuxbridge+Xen: tap devices not detected by neutron-linuxbridge-agent

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in neutron juno series:
  Fix Committed

Bug description:
  When using Xen as hypervisor and the linuxbridge ml2 plugin, the neutron-linuxbridge-agent does not detect added/removed/changed tap devices.
  The reason seems that the agent only searches in /sys/devices/virtual/net for tap devices. In the Xen case, the tap devices don't popup in this directory. The devices are available in /sys/class/net . Also according to the kernel ABI doc (see https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-devices ), /sys/devices should not be used. Instead /sys/class should be used.
