Non-supported Features
The features not yet supported include:
-- Link status change interrupt
-
- Receive queue interupts
- Priority-based flow control
- VLAN stripping
-- Scattered receive
-
- LRO
+Limitations
+-----------
+
+Due to requirements on receive buffer alignment and usage of the receive
+buffer for the auxiliary packet information provided by the NIC up to
+extra 269 (14 bytes prefix plus up to 255 bytes for end padding) bytes may be
+required in the receive buffer.
+It should be taken into account when mbuf pool for receive is created.

Supported NICs
--------------
Case-insensitive 1/y/yes/on or 0/n/no/off may be used to specify
boolean parameters value.
+- ``perf_profile`` [auto|throughput|low-latency] (default **throughput**)
+
+ Choose hardware tunning to be optimized for either throughput or
+ low-latency.
+ **auto** allows NIC firmware to make a choice based on
+ installed licences and firmware variant configured using **sfboot**.
+
- ``debug_init`` [bool] (default **n**)
Enable extra logging during device intialization 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.
