Issue appeared after following commit in ops-switchd-container-plugin:

    STP plugin code for docker environment

In this plugin, STP is implemented using Linux bridge. With this configuration STP is not working properly (storm is observed in https://github.com/MERAprojects/ops-build/issues/29). VLANs are not working also.

If we delete bridge-sim, VLANs are working ok (ping is failed between different VLANs).
