+Netvsc PMD arguments
+--------------------
+
+The user can specify below argument in devargs.
+
+#. ``latency``:
+
+ A netvsc device uses a mailbox page to indicate to the host that there
+ is something in the transmit queue. The host scans this page at a
+ periodic interval. This parameter allows adjusting the value that
+ is used by the host. Smaller values improve transmit latency, and larger
+ values save CPU cycles. This parameter is in microseconds.
+ If the value is too large or too small it will be
+ ignored by the host. (Default: 50)
