Intel X710 card drops broadcast traffic on selected vlans

Solution In Progress - Updated -

Issue

  • We're facing issues on the Intel X710 card where VM's are not able to communicate with other VM's on some (not all!) different nodes.
  • This occurs when initially configuring the affected vlan with NNCP for some vlans.

Environment

  • Openshift Container Platform Virtualization
  • LACP bonding
  • vlans
  • Linux bridge connected to each vlan
  • Intel X710 Network Adapter
    • Inbox i40e driver
      Topology:
VM1------br1------bond.vlan1------+                           +---------------+
                                  |                           |               |
VM2------br2------bond.vlan2------+------bond+------eno3------+               |
                                  |          |                |physical switch|---other hosts
VM3------br3------bond.vlan3------+          +------eno4------+               |
                                                              |               |
                                                              +---------------+
