+Flow API support
+----------------
+
+Supported attributes:
+
+- Ingress
+
+Supported pattern items:
+
+- VOID
+
+- ETH (exact match of source/destination addresses, individual/group match
+ of destination address, EtherType)
+
+- VLAN (exact match of VID, double-tagging is supported)
+
+- IPV4 (exact match of source/destination addresses,
+ IP transport protocol)
+
+- IPV6 (exact match of source/destination addresses,
+ IP transport protocol)
+
+- TCP (exact match of source/destination ports)
+
+- UDP (exact match of source/destination ports)
+
+Supported actions:
+
+- VOID
+
+- QUEUE
+
+Validating flow rules depends on the firmware variant.
+
+Ethernet destinaton individual/group match
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Ethernet item supports I/G matching, if only the corresponding bit is set
+in the mask of destination address. If destinaton address in the spec is
+multicast, it matches all multicast (and broadcast) packets, oherwise it
+matches unicast packets that are not filtered by other flow rules.

Supported NICs
--------------
Case-insensitive 1/y/yes/on or 0/n/no/off may be used to specify
boolean parameters value.
+- ``rx_datapath`` [auto|efx|ef10] (default **auto**)
+
+ Choose receive datapath implementation.
+ **auto** allows the driver itself to make a choice based on firmware
+ features available and required by the datapath implementation.
+ **efx** chooses libefx-based datapath which supports Rx scatter.
+ **ef10** chooses EF10 (SFN7xxx, SFN8xxx) native datapath which is
+ more efficient than libefx-based and provides richer packet type
+ classification, but lacks Rx scatter support.
+
+- ``tx_datapath`` [auto|efx|ef10|ef10_simple] (default **auto**)
+
+ Choose transmit datapath implementation.
+ **auto** allows the driver itself to make a choice based on firmware
+ features available and required by the datapath implementation.
+ **efx** chooses libefx-based datapath which supports VLAN insertion
+ (full-feature firmware variant only), TSO and multi-segment mbufs.
+ **ef10** chooses EF10 (SFN7xxx, SFN8xxx) native datapath which is
+ more efficient than libefx-based but has no VLAN insertion and TSO
+ support yet.
+ **ef10_simple** chooses EF10 (SFN7xxx, SFN8xxx) native datapath which
+ is even more faster then **ef10** but does not support multi-segment
+ mbufs.
+
- ``perf_profile`` [auto|throughput|low-latency] (default **throughput**)
Choose hardware tunning to be optimized for either throughput or
- ``debug_init`` [bool] (default **n**)
- Enable extra logging during device intialization and startup.
+ Enable extra logging during device initialization and startup.
- ``mcdi_logging`` [bool] (default **n**)
Enable extra logging of the communication with the NIC's management CPU.
The logging is done using RTE_LOG() with INFO level and PMD type.
The format is consumed by the Solarflare netlogdecode cross-platform tool.
+
+- ``stats_update_period_ms`` [long] (default **1000**)
+
+ Adjust period in milliseconds to update port hardware statistics.
+ The accepted range is 0 to 65535. The value of **0** may be used
+ to disable periodic statistics update. One should note that it's
+ only possible to set an arbitrary value on SFN8xxx provided that
+ firmware version is 6.2.1.1033 or higher, otherwise any positive
+ value will select a fixed update period of **1000** milliseconds
