sync'ed offline. let's check TH5 for better change in the next PR.

[r12f]

lgtm.

[rick-arista]

Moved this back to draft for a moment. There's an intermittent failure in one of the test cases due to the margin being 0. I'll update this PR after running the tests locally a few times to verify adding a small margin fixes this.

@r12f Done!

[rick-arista]

@Janetxxx I've pushed another small fix that fixes flaky failures in testQosSaiHeadroomPoolWatermark

[Janetxxx]

@rick-arista , I believe we should use topo-t0-standalone-32 here, as it is consistent with our internal setup.

[rick-arista]

These params are generated for the 256 interface config. If you're testing with 32 interfaces I think they should still work, but you'll need to modify this ad hoc.

@rick-arista How do you get pkts_num_trig_pfc: 120117?
