E810 LACP handing

Hi there!

I'm faced with unexpected behavior when try to send LACP packet to port under testpmd control. Here is what I did :

  1. Bind port to igb_uio driver:
    sudo usertools/dpdk-devbind.py --unbind 0000:8b:00.7
    sudo usertools/dpdk-devbind.py  --bind=igb_uio 0000:8b:00.7
  2. Run testpmd:  
    sudo ./dpdk-testpmd --log-level=debug -l 2,3 -- -i
  3. Start forwarding:
    testpmd> start tx_firs
  4. Send from another server LACP packet to port under testpmd control
  5. Show xstats and it's all good for now:
    testpmd> show port xstats 0
    rx_good_packets: 4
    rx_unknown_protocol_packets: 0
  6. reset port 0
    testpmd> stop
    testpmd> port stop 0
    testpmd> port reset 0
    testpmd> port start all
    testpmd> start tx_firs
  7. Send from another server LACP packet to port under testpmd control
  8. Show xstats and see that `rx_unknown_protocol_packets` encountered:
    rx_good_packets: 0
    rx_unknown_protocol_packets: 4

Configuration: E810 NIC, firmware-version: 3.10, DPDK version: 21.11.0.

I don't know if this behavior is normal, but I would like the LACP traffic not to be dropped by the card. Thanks!
