[ovs-dev] [multiple tables 8/8] New action NXAST_RESUBMIT_TABLE.

Tue Aug 9 16:22:29 UTC 2011

Good idea.  I added:

    - ovs-vswitchd:
      - The software switch now supports 255 OpenFlow tables, instead
        of just one.  By default, only table 0 is consulted, but the
        new NXAST_RESUBMIT_TABLE action can look up in additional
        tables.

I'll push this soon.
