    More precise flow table cleaning
    
    OVS-agent wants to clean flows table by table during restart,
    but actually it does not. If one table has same cookie with
    other tables, all related flows will be clean at once.
    
    This patch adds the table_id param to the related call
    to limit the flow clean on one table at once.

Title:
  [ML2][OVS] more precise flow table cleaning

Status in neutron:
  Fix Released

Bug description:
  OVS-agent wants to clean flows table by table during restart, but
  actually it does not. [1] If one table has same cookie with other
  tables, all related flows will be clean at once. A bit radical in such
  style.
