Hi Mostafa,
Port Security functional can be implemented using ACL plugin MACIP feature. On
a given interface, ACLs are applied on input traffic to permit using a mix of
MAC and IP.
Here you will find more detail about it:

Hi,
"tx frame not ready"? means VPP didn't find empty queue at linux side. Linux is
processing too slow which results in that behavior and VPP drops those packets.
While when you use dpdk, you bypass linux kernel (bottleneck), so you don't
find such behavior.
If you still want to use the vi

I am writing regarding a proposal to change API messages related to l2fib mac

array of six bytes to store mac address.
