Applied M. Camp's comments on patchset 4. Also, some additional formatting changes such as tidying line ends <= 79 characters, reformatting very wide ascii table as list table to control line widths, etc. Resolved conflict in _includes/data-networks-overview.rest Change-Id: I8a2a80f21d3630849900e85dc2495da1668648af Signed-off-by: Ron Stone <ronald.stone@windriver.com> Signed-off-by: Stone <ronald.stone@windriver.com>

Data Networks in OpenStack Overview
Data networks are used to model the L2 Networks that nodes' data, pci-sriov and pci-passthrough interfaces attach to.
Note
Data networks are required if you plan to deploy the openstack application or provide SR-IOV network interface access to container workloads.
A Layer 2 physical or virtual network or set of virtual networks is used to provide the underlying network connectivity needed to support the application project networks. Multiple data networks may be configured as required, and realized over the same or different physical networks. Access to external networks is typically granted to the openstack-compute labeled worker nodes using the data network. The extent of this connectivity, including access to the open internet, is application dependent.
Data networks are created at the level. Flat, VLAN and VXLAN type data networks are supported by the virtual switch. For details on creating data networks and assigning them to node interfaces, see the following documentation:
Adding Data Networks Using the CLI <adding-data-networks-using-the-cli>Assigning a Data Network to an Interface <assigning-a-data-network-to-an-interface>Removing a Data Network Using the CLI <removing-a-data-network-using-the-cli>
VXLAN Data Networks are specific to application.
Segmentation ID ranges for VLAN and VXLAN data networks are defined
through OpenStack Neutron commands, see Adding Segmentation Ranges Using the CLI
<adding-segmentation-ranges-using-the-cli>.
