Reusing ixgbe VLAN+macvlan VF with different MAC results in incorrect spoofchk message at PF

Issue

• Reusing ixgbe VLAN+macvlan VF with different MAC results in incorrect spoofchk message at PF
• Communication is not working between two VFs from the same PF in the virtualized environment.
• Setup as follows:
  • VF1 is attached to VM1.
  • VF2 was attached to an old VM which ran a container. The container had a macvlan interface on top of the VM interface. This container VM required trust enabled on VF2 in the hypervisor. That old container VM is gone now.
  • VF2 is now attached to VM2.
  • VF1 has a VLAN interface inside (eg: eth0.100) and VF2 tags the VLAN on the VF.
  • The old container VM, its macvlan interface, and VM2 have different MAC addresses for the VF.
  • Assign the IP address for both VFs inside VMs.
  • Try to ping either VM1 to VM2 or VM2 to VM1. Communication won't work.
• Spoofed packet message logged in hypervisor, eg:

kernel: ixgbe 0000:xx:xx.x ethX: 2 Spoofed packets detected
