Let's use dynamic mode and dynamic_th -8 for creating profile. this is what was used before
L 689
attr.value.u32 = SAI_BUFFER_POOL_THRESHOLD_MODE_DYNAMIC;
L 711
attr.value.u32 = SAI_BUFFER_PROFILE_THRESHOLD_MODE_DYNAMIC;
L 718~719
attr.id = SAI_BUFFER_PROFILE_ATTR_SHARED_DYNAMIC_TH;
attr.value.s8 = 0;

…storm is detected (#2304) What I did Avoid dropping traffic that is ingressing the port/pg that is in storm. The code changes in this PR avoid creating the ingress zero pool and profile and does not attach any zero profile to the ingress pg when pfcwd is triggered Revert changes related to #1480 where the retry mechanism was added to BufferOrch which caches the task retries and while the PG is locked by PfcWdZeroBufferHandler. Revert changes related to #2164 in PfcWdZeroBufferHandler & ZeroBufferProfile & BufferOrch. Updated UT's accordingly How I verified it UT's. Ran the sonic-mgmt test with these changes sonic-net/sonic-mgmt#5665 and verified if they've passed. Signed-off-by: Vivek Reddy Karri <[email protected]>
