…n T2 uplinks (sonic-net#16690) Microsoft ADO (25266920) sonic-mgmt xoff test was failing for [100g,120km]. Needed to update total headroom pool size when 100G line card is used as T2 uplink. This size was calculated assuming 100g is used for downlink so cable length was 2km whereas it can also be used for uplink (cable length - 120km). so we need to do calculation based on 120km not 2km. Although it will be some wastage for 2km scenario but it should cover both cases.
