+- Packet type information
+- Promiscuous mode
+- Jumbo frames
+- SR-IOV VF
+- Lock-free Tx queue
+- Multiple queues for TX and RX
+- Receiver Side Scaling (RSS)
+- MAC/VLAN filtering
+- Generic flow API
+- VLAN/QinQ stripping and insertion
+- Port hardware statistics
+- Link state information
+- Link flow control
+- Scatter-Gather IO support
+- Vector Poll mode driver
+- Debug utilities - Context dump and error interrupt support
+- IEEE1588 timestamping
Prerequisites
-------------
- ``CONFIG_RTE_LIBRTE_OCTEONTX2_PMD`` (default ``y``)
Toggle compilation of the ``librte_pmd_octeontx2`` driver.
+
+Runtime Config Options
+----------------------
+
+- ``HW offload ptype parsing disable`` (default ``0``)
+
+ Packet type parsing is HW offloaded by default and this feature may be toggled
+ using ``ptype_disable`` ``devargs`` parameter.
+
+- ``Rx&Tx scalar mode enable`` (default ``0``)
+
+ Ethdev supports both scalar and vector mode, it may be selected at runtime
+ using ``scalar_enable`` ``devargs`` parameter.
+
+- ``RSS reta size`` (default ``64``)
+
+ RSS redirection table size may be configured during runtime using ``reta_size``
+ ``devargs`` parameter.
+
+ For example::
+
+ -w 0002:02:00.0,reta_size=256
+
+ With the above configuration, reta table of size 256 is populated.
+
+- ``Flow priority levels`` (default ``3``)
+
+ RTE Flow priority levels can be configured during runtime using
+ ``flow_max_priority`` ``devargs`` parameter.
+
+ For example::
+
+ -w 0002:02:00.0,flow_max_priority=10
+
+ With the above configuration, priority level was set to 10 (0-9). Max
+ priority level supported is 32.
+
+- ``Reserve Flow entries`` (default ``8``)
+
+ RTE flow entries can be pre allocated and the size of pre allocation can be
+ selected runtime using ``flow_prealloc_size`` ``devargs`` parameter.
+
+ For example::
+
+ -w 0002:02:00.0,flow_prealloc_size=4
+
+ With the above configuration, pre alloc size was set to 4. Max pre alloc
+ size supported is 32.
+
+- ``Max SQB buffer count`` (default ``512``)
+
+ Send queue descriptor buffer count may be limited during runtime using
+ ``max_sqb_count`` ``devargs`` parameter.
+
+ For example::
+
+ -w 0002:02:00.0,max_sqb_count=64
+
+ With the above configuration, each send queue's decscriptor buffer count is
+ limited to a maximum of 64 buffers.
+
+
+.. note::
+
+ Above devarg parameters are configurable per device, user needs to pass the
+ parameters to all the PCIe devices if application requires to configure on
+ all the ethdev ports.
