Why I did it dhcp_relay/test_dhcp_relay_stress.py::test_dhcp_relay_stress[offer|ack] tests are failing on dualtor topologies with signature Failed: /tmp/dhcp_stress_test_offer.json is missing, see issue aristanetworks/sonic-qual.msft#325 for more details. Work item tracking Microsoft ADO (number only): How I did it count_matched_packets method is getting stuck in a while loop as long as ptf server port receives any packet (Ex: in dualtor case, we do see continuous ICMP packets on ptf port). Fix is to consider only expected packets w.r.t timeout (similar to count_matched_packets_all_ports logic). How to verify it With this PR changes we should not see dhcp_relay/test_dhcp_relay_stress.py failures on dualtor topologies with symptom Failed: /tmp/dhcp_stress_test_offer.json is missing.
