+VF & TC max bandwidth setting
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The per VF max bandwidth and per TC max bandwidth cannot be enabled in parallel.
+The dehavior is different when handling per VF and per TC max bandwidth setting.
+When enabling per VF max bandwidth, SW will check if per TC max bandwidth is
+enabled. If so, return failure.
+When enabling per TC max bandwidth, SW will check if per VF max bandwidth
+is enabled. If so, disable per VF max bandwidth and continue with per TC max
+bandwidth setting.
+
+TC TX scheduling mode setting
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There're 2 TX scheduling modes for TCs, round robin and strict priority mode.
+If a TC is set to strict priority mode, it can consume unlimited bandwidth.
+It means if APP has set the max bandwidth for that TC, it comes to no
+effect.
+It's suggested to set the strict priority mode for a TC that is latency
+sensitive but no consuming much bandwidth.
