Markos Chandras e6bd8f037c Accepting request 461859 from home:markoschandras:network 
- Version bump to 2.7.0 (fate#321541). Some of the changes are:
  * Utilities and daemons that support SSL now allow protocols and
    ciphers to be configured with --ssl-protocols and --ssl-ciphers.
  * OVN:
    - QoS is now implemented via egress shaping rather than ingress policing.
    - DSCP marking is now supported, via the new northbound QoS table.
    - IPAM now supports fixed MAC addresses.
    - Support for source IP address based routing.
    - ovn-trace:
      * New --ovs option to also print OpenFlow flows.
      * put_dhcp_opts and put_dhcp_optsv6 actions may now be traced.
    - Support for managing SSL and remote connection configuration in
      northbound and southbound databases.
  * Fixed regression in table stats maintenance introduced in OVS
    2.3.0, wherein the number of OpenFlow table hits and misses was
    not accurate.
  * OpenFlow:
    - OFPT_PACKET_OUT messages are now supported in bundles.
    - A new "selection_method=dp_hash" type for OpenFlow select group
      bucket selection that uses the datapath computed 5-tuple hash
      without making datapath flows match the 5-tuple fields, which
      is useful for more efficient load balancing, for example.  This
      uses the Netronome extension to OpenFlow 1.5+ that allows
      control over the OpenFlow select groups selection method.  See
      "selection_method" and related options in ovs-ofctl(8) for
      details.
    - The "sample" action now supports "ingress" and "egress" options.
    - The "ct" action now supports the TFTP ALG where support is available.
    - New actions "clone" and "ct_clear".
  * ovs-ofctl:

Subject: [PATCH] utilities: Add script to support DPDK option migration from
OvS<2.6
Open vSwitch 2.6 now requires DPDK options to be in the Open vSwitch
database so add a script to migration options from
/etc/sysconfig/openvswitch to the database.

initialization from cmdline to db")
