-a af:00.0,pps_out='[pin:0]'
+- ``Low Rx latency`` (default ``0``)
+
+ vRAN workloads require low latency DPDK interface for the front haul
+ interface connection to Radio. By specifying ``1`` for parameter
+ ``rx_low_latency``, each completed Rx descriptor can be written immediately
+ to host memory and the Rx interrupt latency can be reduced to 2us::
+
+ -a 0000:88:00.0,rx_low_latency=1
+
+ As a trade-off, this configuration may cause the packet processing performance
+ degradation due to the PCI bandwidth limitation.
