waleedm 3144a8fc4f Support binding VFs after moving to switchdev 
Currently for Mellanox vendor ID we don't bind vfs after moving to switchdev
because it affects VF-lAG feature, but for other features like OVS-DPDK SRIOV,
OVS-DPDK VDPA and OVS-Kernel Forwarder we have to bind them.

To support binding VFs to networking driver, there are two scenarios
that we need to address:
    * Deployment case
      In deployment case, we are binding vfs after moving all the
      sriov_pfs to switchdev and also configuring sriov_bind service
    * Reboot case
      In reboot case, we start sriov_bind service which will run
      after network.service sriov_config.service (The case that we are
      sure that VF-LAG activation done)

os-net-config

host network configuration tool

An implementation of the 'network configuration' spec @ https://review.opendev.org/#/c/97859/. The intention is for this code to be moved under the tripleo project in due course.

Release Notes

Features

The core aim of this project is to allow fine grained (but extendable) configuration of the networking parameters for a network host. The project consists of:

  • A CLI (os-net-config) which provides configuration via a YAML or JSON file formats. By default os-net-config uses a YAML config file located at /etc/os-net-config/config.yaml. This can be customized via the --config-file CLI option.
  • A python library which provides configuration via an object model.

YAML Config Examples

  • Configure an OVS bridge with a single attached interface (port)

    network_config:
  - 
    type: ovs_bridge
    name: br-ctlplane
    use_dhcp: true
    ovs_extra:
      - br-set-external-id br-ctlplane bridge-id br-ctlplane
    members:
      - 
        type: interface
        name: em1

  • Configure an OVS bridge on top of an OVS bond

    network_config:
  - 
     type: ovs_bridge
     name: br-ctlplane
     use_dhcp: true
     members:
       - 
         type: ovs_bond
         name: bond1
         members:
           - 
             type: interface
             name: em1
           - 
             type: interface
             name: em2

  • Configure a tagged VLAN interface on top of an OVS bridge

    network_config:
  - 
    type: ovs_bridge
    name: br-ctlplane
    use_dhcp: true
    members:
      - 
        type: interface
        name: em1
      - 
        type: vlan
        vlan_id: 16
        addresses:
          - 
            ip_netmask: 192.0.2.1/24

Provider Configuration

Providers are use to apply (implement) the desired configuration on the host system. By default 3 providers are implemented:

  • Ifcfg: persistent network config format stored in /etc/sysconfig/network-scripts
  • ENI: persistent network config format stored in /etc/network/interfaces
  • iproute2: non-persistent provider which implements the config using iproute2, vconfig, etc... (implementation in progress)

When using bin/os-net-config the provider is automatically selected based on the host systems perferred persistent network type (ifcfg or ENI). This can be customized via the --provider CLI option.
