+ICE Poll Mode Driver
+======================
+
+The ice PMD (librte_pmd_ice) provides poll mode driver support for
+10/25 Gbps Intel® Ethernet 810 Series Network Adapters based on
+the Intel Ethernet Controller E810.
+
+
+Prerequisites
+-------------
+
+- Identifying your adapter using `Intel Support
+  <http://www.intel.com/support>`_ and get the latest NVM/FW images.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+- To get better performance on Intel platforms, please follow the "How to get best performance with NICs on Intel platforms"
+  section of the :ref:`Getting Started Guide for Linux <linux_gsg>`.
+
+
+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_ICE_PMD`` (default ``y``)
+
+  Toggle compilation of the ``librte_pmd_ice`` driver.
+
+- ``CONFIG_RTE_LIBRTE_ICE_DEBUG_*`` (default ``n``)
+
+  Toggle display of generic debugging messages.
+
+- ``CONFIG_RTE_LIBRTE_ICE_RX_ALLOW_BULK_ALLOC`` (default ``y``)
+
+  Toggle bulk allocation for RX.
+
+- ``CONFIG_RTE_LIBRTE_ICE_16BYTE_RX_DESC`` (default ``n``)
+
+  Toggle to use a 16-byte RX descriptor, by default the RX descriptor is 32 byte.
+
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+
+Sample Application Notes
+------------------------
+
+Vlan filter
+~~~~~~~~~~~
+
+Vlan filter only works when Promiscuous mode is off.
+
+To start ``testpmd``, and add vlan 10 to port 0:
+
+.. code-block:: console
+
+    ./app/testpmd -l 0-15 -n 4 -- -i
+    ...
+
+    testpmd> rx_vlan add 10 0
+
+
+Limitations or Known issues
+---------------------------
+
+19.02 limitation
+~~~~~~~~~~~~~~~~
+
+Ice code released in 19.02 is for evaluation only.
+
+
+Secondary Process
+~~~~~~~~~~~~~~~~~
+Ice supports secondary process. But it does not support changing the setting
+and configuration in the secondary process.
+
+
+Promiscuous mode not supported
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+As promiscuous mode is not supported as this stage, a port can only receive the
+packets which destination MAC address is this port's own.
+
+
+TX anti-spoofing cannot be disabled
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+TX anti-spoofing is enabled by default. At this stage it's not supported to
+disable it. So any TX packet which source MAC address is not this port's own
+will be dropped by HW. It means io-fwd is not supported now. Recommand to use
+MAC-fwd for evaluation.
