OVS Kernel - VF LAG Configuration

1. Make sure that the compute.yaml file has a Linux bond: 

     name: bond0
     type: linux_bond
     bonding_options: "mode=active-backup miimon=100"
     addresses:
       - ip_netmask: {{ tenant_ip ~ '/' ~ tenant_cidr }}
     members:
     - type: sriov_pf
       name: enp3s0f0
       link_mode: switchdev
       numvfs: 64
       promisc: true
       use_dhcp: false
     - type: sriov_pf
       name: enp3s0f1
       link_mode: switchdev
       numvfs: 64
       promisc: true
       use_dhcp: false

2. Make sure the /usr/share/openstack-tripleo-heat-templates/environments/ovs-hw-offload.yaml file has hw-offloading enabled:
   

   ComputeSriovParameters:
     OvsHwOffload: True

3. Configure the bonding option in the same file:
   

   parameter_defaults:
      BondInterfaceOvsOptions: "mode=active-backup miimon=100"

   The supported bonding modes for vf-lag are:

• Active-Backup
• Active-Active
• LACP

Following is an example of an uplink over a VLAN number 77 in a bond use:

- type: interface
  name: bond0.77
  use_dhcp: false
       addresses:
      - ip_netmask: {{ tenant_ip ~ '/' ~ tenant_cidr }}

Following is an example of an uplink of a general interface:

- type: interface
  name: enp2s0f1.7
  use_dhcp: false
     addresses:
     - ip_netmask: {{ tenant_ip ~ '/' ~ tenant_cidr }}
