Prerequisites
-------------
-- The E810 is currently in sampling state only. To obtain early samples and/or get further information
- about kernel drivers, firmware and DDP support, please speak to your Intel representative.
-
- 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"
-w 80:00.0,pipeline-mode-support=1
-- ``Flow Mark Support`` (default ``0``)
-
- This is a hint to the driver to select the data path that supports flow mark extraction
- by default.
- NOTE: This is an experimental devarg, it will be removed when any of below conditions
- is ready.
- 1) all data paths support flow mark (currently vPMD does not)
- 2) a new offload like RTE_DEV_RX_OFFLOAD_FLOW_MARK be introduced as a standard way to hint.
- Example::
-
- -w 80:00.0,flow-mark-support=1
-
- ``Protocol extraction for per queue``
Configure the RX queues to do protocol extraction into mbuf for protocol
The grouping ``()`` can be omitted for single element group. If no queues are
specified, PMD will use this protocol extraction type for all queues.
- Protocol is : ``vlan, ipv4, ipv6, ipv6_flow, tcp``.
+ Protocol is : ``vlan, ipv4, ipv6, ipv6_flow, tcp, ip_offset``.
.. code-block:: console
TCPHDR2 - Reserved
+ .. table:: Protocol extraction : ``ip_offset``
+
+ +----------------------------+----------------------------+
+ | IPHDR2 | IPHDR1 |
+ +============================+============================+
+ | IPv6 HDR Offset | IPv4 HDR Offset |
+ +----------------------------+----------------------------+
+
+ IPHDR1 - Outer/Single IPv4 Header offset.
+
+ IPHDR2 - Outer/Single IPv6 Header offset.
+
Use ``rte_net_ice_dynf_proto_xtr_metadata_get`` to access the protocol
extraction metadata, and use ``RTE_PKT_RX_DYNF_PROTO_XTR_*`` to get the
metadata type of ``struct rte_mbuf::ol_flags``.
A symbolic link to the DDP package file is also ok. The same package
file is used by both the kernel driver and the DPDK PMD.
