Bug description:
  1. Release

  $ lsb_release -rd
  Description:    Ubuntu 16.04.3 LTS
  Release:        16.04

  2. Package version, 2.5.2 was the culprit

  $ apt-cache policy openvswitch-common
  openvswitch-common:
    Installed: 2.8.0-1
    Candidate: 2.8.0-1
    Version table:
   *** 2.8.0-1 100
          100 /var/lib/dpkg/status
       2.5.2-0ubuntu0.16.04.1 500
          500 http://fi.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages
       2.5.0-0ubuntu1 500
          500 http://fi.archive.ubuntu.com/ubuntu xenial/main amd64 Packages

  3. Expected

  To have a network without broadcast storms / loops so it becomes
  stable.

  4. What happened.

  The network crashed, probably the TP-Link switch which could not
  understand a buggy RSTP implementation.

  5. Detailed description.

  In version 2.5.2 when enabling rstp then it crashes the network when
  connected to rstp port in a TP-Link SG3424 switch. The port in TP-Link
  gets status error.

  Upgraded ovs to 2.8.0 by compiling myself and it started to work as
  expected.

  6. Suggestions.

  So perhaps dont allow rstp in 2.5.x or upgrade the package?
