Regarding the DKMS build error, it seems to be related to the following entries in the changelog :

    - "configure" option --with-l26 has been renamed --with-linux, and
      --with-l26-source has been renamed --with-linux-source. The old
      names will be removed after the next release, so please update
      your scripts.
    - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and
      datapath/linux-2.6/compat-2.6 directories.

The DKMS support that I just committed to the upstream Git "master" for Open vSwitch has this bug fixed (s/linux-2.6/linux/ as suggested in comment #3).

Excellent, many thanks

num-threads set to 1 disables threading, setting to 0 causes a segfault rather than the config parser flagging it as an error.
