+- ``Flow Mark Support`` (default ``0``)
+
+ This is a hint to the driver to select the data path that supports flow mark extraction
+ by default.
+ NOTE: This is an experimental devarg, it will be removed when any of below conditions
+ is ready.
+ 1) all data paths support flow mark (currently vPMD does not)
+ 2) a new offload like RTE_DEV_RX_OFFLOAD_FLOW_MARK be introduced as a standard way to hint.
+ Example::
+
+ -w 80:00.0,flow-mark-support=1
