stx.4.0 Features
- TSN support in Container
        - Prime: Shuicheng / Yi C
        - Story: https://storyboard.openstack.org/#!/story/2006746 
        - Status: Starting - setting up environment, but not much progress on feature yet
        - The hard dependency on the host kernel being 4.19 is required for regular containers, but not kata containers. Can proceed with work for kata containers.
        - From Yi C:
                 - NIC driver should be okay given IGB (Intel I210) is already there. To support TSN, we still need some kernel features, for example,
                         - Qdisc TAPRIO: implemented TSN protocol 802.1Qbv and was introduced in Linux 4.20
                         - Qdisc CBS: implemented 802.1Qav and was introduced in Linux 4.15
                         - probably other features like AF_XDP socket family which was introduced in Linux 4.18.
                 - For the feature of " TSN support in Kata", since Kata container has its own kernel, there is not hard dependency with CentOS 8 upgrade task
        - Is there any code for this? or just a procedure?

- IPv6 PXE boot network support
        - Prime: Kunpeng Zhang - 99cloud
        - Story: https://storyboard.openstack.org/#!/story/2006442 
        - Status: Not Started
        - Received email from Kunpeng on March 5 indicating that he will provide the plan for this feature shortly.

- OVS-DPDK Containerization in StarlingX
        - Story: https://storyboard.openstack.org/#!/story/2005496 
        - Status: Out of stx.4.0
        - As per Huifeng Le, the detailed status when the feature was put on hold is as follows:
                 - Openstack-helm:
                         - Wait for merge:
                         - Override configurations more than conf section.( https://review.opendev.org/#/c/701676/)
                         - Ongoing:
                         - 1. Make more sections in daemonset overridable.( https://review.opendev.org/#/c/707788/) ? code ready, work on CI
                         - 2. Modify files related to overrides.( https://review.opendev.org/#/c/707775/) ? code ready, work on CI
                         - 3. Ovs per-host overrides support. (https://review.opendev.org/#/c/703639/) ? 50% done
                 - Starlingx:
                         - Ongoing:
                         - Add dpdk parameters for openvswitch.(https://review.opendev.org/#/c/694188/)
                         - This patch depends on the openstack-helm patch.
                 - Todo:
                         - Add dpdk parameters for NEUTRON.

stx.4.0 Bugs
- Total: 4
- https://bugs.launchpad.net/starlingx/+bug/1862651  -- IPv6 DC: 100.113 alarm "'DATA-NETWORK0' interface failed" raised at both system controller and subclouds after installation
        - New. Issue appears to be related to having multiple data ports. Not assigned yet. 
- https://bugs.launchpad.net/starlingx/+bug/1833463  -- armada-manifest upload failed when configuring bond with OVS container (vswitch-type=none)
        - Needs to be re-assigned. Action with Yong. Work is related to openstack-helm
- https://bugs.launchpad.net/starlingx/+bug/1850438  -- The sriov device plugin pod may start before it's config manifest is written
        - Steve. On hold. As per Steve, he hasn't been seeing this issue in recent testing. The race condition still exists, but is happening at a much lower frequency.
