Spoofed packets detected

I am new to ESXi and therefore may not be familiar with most of the VMWARE terminology. Please correct me if I am wrong because it is how I would learn.

Background

1. I installed ESXi 6.5 on a Dell PowerEdge R630 with a 2-port 82599EB 10G NIC.
2. I installed two CentOS 7 VMs with DPDK.

SR-IOV Configuration

1. I am using SR-IOV on the NIC ports. On each of the VM, I created a new network adapter on the first VM as follows with one Virtual Function.
   1. Network Adapter 1: 10G port group 1
   • Adapter Type: SR-IOV passthrough
   • Physical function: 82599EB 10-Gigabit SFI/SFP+ Network Connection - 0000:82:00.0
   • MAC Address: Automatic
   • Guest OS MTU Change: Disallow
2. On top of the creation of the new adapter, I also reserved some memory as required by SR-IOV.
3. I did the same on the second VM.
   1. Network Adapter 1: 10G port group 2
      • Adapter Type: SR-IOV passthrough
   • Physical function: 82599EB 10-Gigabit SFI/SFP+ Network Connection - 0000:82:00.1
   • MAC Address: Automatic
   • Guest OS MTU Change: Disallow
4. Of course, each 10G port group is linked to a standard virtual group which in turn is linked to a 82599EB 10G port (Uplink Port)

Traffic Generation

1. I have a PCAP file which has packets with different MAC addresses than the DPDK interface on the first VM.
2. I generated a constant traffic from the first VM to the second VM using the PCAP file and none was received on the second VM.
3. I sshed to the ESXI host and ran dmesg andgot the following error messages repeatedly:
   •      2018-05-04T23:39:00.679Z cpu31:66145)<4>ixgbe 0000:82:00.0: vmnic4: 512 Spoofed packets detected
4. I googled this error and somewhat have concluded that this error may have something to do with the MAC Spoofing feature on the 82599EB 10G NIC card. How do I disable it?
5. The 82599EB 10G NIC card using esxcli displays the following information:
