This function should be moved to tests/common/platform/interface_utils.py
But do it with another PR.

There are lots of helper functions can be moved to tests/common under various folders. Please put up another PR for coding sharing.

Summary: Two pytest tests:
Type of change
Approach
How did you do it?
Set up the testbed, including (1) copy the PFC packet generator toe the leaf fanout switches, and (2) copying the PTF script to the PTF container.
Given a tested interface i on the DUT, we generate PFC pause frames at the leaf fanout to block the lossless priority p of this interface.
The PTF script transmits two packets which should leave DUT from the interface i. One packet is mapped to priority p. The other packet is mapped to any other priority.
The PTF script should only receive the packet that is not mapped to priority p.
How did you verify/test it?
I ran this test case in our testbed.
Any platform specific information?
N/A
Supported testbed topology if it's a new test case?
Currently, the test case only supports T0 topology. I will add more topologies in the future.
