Approach

What is the motivation for this PR?

The purpose of this test is to conduct a DHCP stress test with CoPP policy, ensuring that the DHCP relay service can withstand the maximum load applied to the CPU

How did you do it?

In the test, we will generate packets at a rate of 10,000 packets per second for 120 seconds to ensure the DHCP relay service can handle the maximum load without failure.

How did you verify/test it?

In the test log file, we will record the number of packets sent and received via the discover, offer, request, and ack stages, noting that all of them are sent by broadcast. Meanwhile, we can manually check the device to monitor the status of the DHCP container, resource utilization, and verify that the DHCP processes are running.

Any platform specific information?

Supported testbed topology if it's a new test case?
