    - NSH implementation now conforms to latest draft (draft-ietf-sfc-nsh-28).
    - Bug fixes

0006-adapt-ovs-scripts.patch was splited into two separate patches as
the original patch does not apply against 2.8.2 anymore.  Other patches
are just re-numbered without actual function change

Open vSwitch needs to run python on build machine to make build-time
required files.  python-six library is only required by the openvswitch
python library on target machine, not a build dependency.

We override host PYTHONPATH by overriding it in MAKE_VARS.  This way we
can remove 0003-override-pythonpath-via-make-vars.patch

This also fixes shebang wrongly pointing to python on host
