Limitations
-----------
+- Windows support:
+
+ On Windows, the features are limited:
+
+ - Promiscuous mode is not supported
+ - The following rules are supported:
+
+ - IPv4/UDP with CVLAN filtering
+ - Unicast MAC filtering
+
- For secondary process:
- Forked secondary process not supported.
- OAM
- protocol type
- options length
- Currently, the only supported options length value is 0.
+
+- Match on Geneve TLV option is supported on the following fields:
+
+ - Class
+ - Type
+ - Length
+ - Data
+
+ Only one Class/Type/Length Geneve TLV option is supported per shared device.
+ Class/Type/Length fields must be specified as well as masks.
+ Class/Type/Length specified masks must be full.
+ Matching Geneve TLV option without specifying data is not supported.
+ Matching Geneve TLV option with ``data & mask == 0`` is not supported.
- VF: flow rules created on VF devices can only match traffic targeted at the
configured MAC addresses (see ``rte_eth_dev_mac_addr_add()``).
- msg_type
- teid
+- Match on GTP extension header only for GTP PDU session container (next
+ extension header type = 0x85).
+- Match on GTP extension header is not supported in group 0.
+
- No Tx metadata go to the E-Switch steering domain for the Flow group 0.
The flows within group 0 and set metadata action are rejected by hardware.

+
+Compilation Prerequisites
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+DevX SDK installation
+^^^^^^^^^^^^^^^^^^^^^
+
+The DevX SDK must be installed on the machine building the Windows PMD.
+Additional information can be found at
+`How to Integrate Windows DevX in Your Development Environment
+<https://docs.mellanox.com/display/winof2v250/RShim+Drivers+and+Usage#RShimDriversandUsage-DevXInterface>`__.
+
+Runtime Prerequisites
+~~~~~~~~~~~~~~~~~~~~~
+
+WinOF2 version 2.60 or higher must be installed on the machine.
+
+WinOF2 installation
+^^^^^^^^^^^^^^^^^^^
+
+The driver can be downloaded from the following site:
+`WINOF2
+<https://www.mellanox.com/products/adapter-software/ethernet/windows/winof-2>`__
+
+DevX Enablement
+^^^^^^^^^^^^^^^
+
+DevX for Windows must be enabled in the Windows registry.
+The keys ``DevxEnabled`` and ``DevxFsRules`` must be set.
+Additional information can be found in the WinOF2 user manual.
