Refactor SR-IOV VF configuration support to use sriov-netplan-shim to configure VF's on PF's so the charm simply writes out the required interfaces.yaml file and restarts the sriov-netplan-shim service which is fully idempotent. Change-Id: I7a3ddf91d4b2ae6aa0806d97c45b59e8a951f67f

Ports provided can be the name or MAC address of the interface to be

added to the bridge. If MAC addresses are used, you may provide multiple

bridge:mac for the same bridge so as to be able to configure multiple

units. In this case the charm will run through the provided MAC addresses

for each bridge until it finds one it can resolve to an interface name.
|

Port can also be a linuxbridge bridge. In this case a veth pair will be

created, the ovs bridge and the linuxbridge bridge will be connected. It

can be useful to connect the ovs bridge to juju bridge.

|
- balance-slb - Considered as a static load-balancing mode. Traffic is load
|
|
balanced between member ports based on the source MAC and VLAN.
|
|
- balance-tcp - This is the preferred bonding mode. It offers traffic load
|
|
balancing based on 5-tuple header fields. LACP must be enabled
|
|
at both endpoints to use this mode. The aggregate link will

fall back to default mode (active-passive) in the event of LACP

use-dvr-snat:

type: boolean

|
|
description: |
|
|
This option controls a mode of the l3 agent when DVR is used. There are
|
|
2 modes 'dvr' (default) and dvr_snat (gateway mode). Neutron server
|
|
(deployed by neutron-api charm) will schedule a network:router_centralized_snat port
|
|
and a (centralized) snat namespace to dvr_snat mode agents only. If this option
|
|
is enabled, all neutron-openvswitch nodes become candidates for being centralized
|
|
snat nodes. If l3ha is enabled on neutron-api, relevant packages are also installed
|
|
on every unit making them capable of hosting parts of an L3HA router. The min and max
|
|
numbers of L3 agents per router need to be taken into account in this case
|
|
(see max_l3_agents_per_router and min_l3_agents_per_router Neutron options).
|
|
Practically, this option can be used to allow DVR routers (L3HA or not) to
|
|
be scheduled without a requirement for a dedicated network node to host
|
|
centralized SNAT. This is especially important if only floating IPs are
|
|
used in the network design and SNAT traffic is minimal or non-existent.
