+- ``Enable validation for VF message`` (default ``not enabled``)
+
+ The PF counts messages from each VF. If in any period of seconds the message
+ statistic from a VF exceeds maximal limitation, the PF will ignore any new message
+ from that VF for some seconds.
+ Format -- "maximal-message@period-seconds:ignore-seconds"
+ For example::
+
+ -w 84:00.0,vf_msg_cfg=80@120:180
