When Punting the ARP packet to the controller, the controller is sending packet_out for all switch ports including the packets ingress port. As a result of which the switch is throwing error in its logs as below:

Test Case:
=========
-> Connect two switches with 2 nodes connecte respectively to the controller
->Install flow in the switches to punt the arp packet to the controller with max length as 65535.

{table="0", match="oxm

{eth_type="0x806"}

", dur_s="114", dur_ns="413000", prio="2", idle_to="1000", hard_to="1200", cookie="0x1", pkt_cnt="36", byte_cnt="1512", insts=[apply{acts=[out

{port="ctrl", mlen="65535"}

]}]},

-> Ping from host1 to host2.

The switch receives a packet out with the output action to the ingress port of the arp packet in the switch.

Attaching the packet capture.Please refer to frame number 4.
