+Solarflare libefx-based Poll Mode Driver
+========================================
+
+The SFC EFX PMD (**librte_pmd_sfc_efx**) provides poll mode driver support
+for **Solarflare SFN7xxx and SFN8xxx** family of 10/40 Gbps adapters.
+SFC EFX PMD has support for the latest Linux and FreeBSD operating systems.
+
+More information can be found at `Solarflare Communications website
+<http://solarflare.com>`_.
+
+
+Supported NICs
+--------------
+
+- Solarflare Flareon [Ultra] Server Adapters:
+
+ - Solarflare SFN8522 Dual Port SFP+ Server Adapter
+
+ - Solarflare SFN8542 Dual Port QSFP+ Server Adapter
+
+ - Solarflare SFN7002F Dual Port SFP+ Server Adapter
+
+ - Solarflare SFN7004F Quad Port SFP+ Server Adapter
+
+ - Solarflare SFN7042Q Dual Port QSFP+ Server Adapter

+ - Solarflare SFN7124F Quad Port SFP+ Server Adapter
+
+ - Solarflare SFN7142Q Dual Port QSFP+ Server Adapter
+
+ - Solarflare SFN7322F Precision Time Synchronization Server Adapter
+
+
+Prerequisites
+-------------
+
+- Requires firmware version:
+
+ - SFN7xxx: **4.7.1.1001** or higher
+
+ - SFN8xxx: **6.0.2.1004** or higher
+
+Visit `Solarflare Support Downloads <https://support.solarflare.com>`_ to get
+Solarflare Utilities (either Linux or FreeBSD) with the latest firmware.
+Follow instructions from Solarflare Server Adapter User's Guide to
+update firmware and configure the adapter.
+
+
+Pre-Installation Configuration
+------------------------------
+
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``.config`` file.
+Please note that enabling debugging options may affect system performance.
+
+- ``CONFIG_RTE_LIBRTE_SFC_EFX_PMD`` (default **y**)
+
+ Enable compilation of Solarflare libefx-based poll-mode driver.
+
+- ``CONFIG_RTE_LIBRTE_SFC_EFX_DEBUG`` (default **n**)
+
+ Enable compilation of the extra run-time consistency checks.
+
+
+Per-Device Parameters
+~~~~~~~~~~~~~~~~~~~~~
+
+The following per-device parameters can be passed via EAL PCI device
+whitelist option like "-w 02:00.0,arg1=value1,...".
+
+Case-insensitive 1/y/yes/on or 0/n/no/off may be used to specify
+boolean parameters value.
+
+- ``debug_init`` [bool] (default **n**)
+
+ Enable extra logging during device intialization and startup.
