IXGBE Driver
============
They are transparently registered at runtime RX/TX execution if all condition checks pass.
1. To date, only an SSE version of IX GBE vPMD is available.
- To ensure that vPMD is in the binary code, ensure that the option CONFIG_RTE_IXGBE_INC_VECTOR=y is in the configure file.
Some constraints apply as pre-conditions for specific optimizations on bulk packet transfers.
The following sections explain RX and TX constraints in the vPMD.
RX Constraints
~~~~~~~~~~~~~~
-Prerequisites and Pre-conditions
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Linux Prerequisites and Pre-conditions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The following prerequisites apply:
By default, IXGBE_MAX_RING_DESC is set to 4096 and RTE_PMD_IXGBE_RX_MAX_BURST is set to 32.
+Windows Prerequisites and Pre-conditions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Follow the :doc:`guide for Windows <../windows_gsg/run_apps>`
+ to setup the basic DPDK environment.
+
+- Identify the Intel\ |reg| Ethernet adapter and get the latest NVM/FW version.
+
+- To access any Intel\ |reg| Ethernet hardware,
+ load the NetUIO driver in place of existing built-in (inbox) driver.
+
+- To load NetUIO driver, follow the steps mentioned in `dpdk-kmods repository
+ <https://git.dpdk.org/dpdk-kmods/tree/windows/netuio/README.rst>`_.
+
+- Loading of private Dynamic Device Personalization (DDP) package
+ is not supported on Windows.
+
+
Feature not Supported by RX Vector PMD
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: console
- testpmd -w af:10.0,pflink_fullchk=1 -- -i
+ dpdk-testpmd -a af:10.0,pflink_fullchk=1 -- -i
- ``pflink_fullchk`` (default **0**)
``nointxmask=1`` to load ``vfio`` module if the intx is not shared with other
devices.
+RSS isn't supported when QinQ is enabled
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Due to FW limitation, IXGBE doesn't support RSS when QinQ is enabled currently.
+
+UDP with zero checksum is reported as error
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Intel 82599 10 Gigabit Ethernet Controller Specification Update (Revision 2.87)
+Errata: 44 Integrity Error Reported for IPv4/UDP Packets With Zero Checksum
+
+To support UDP zero checksum, the zero and bad UDP checksum packet is marked as
+PKT_RX_L4_CKSUM_UNKNOWN, so the application needs to recompute the checksum to
+validate it.
+
Inline crypto processing support
--------------------------------
port representors for on initialization of the PF PMD by passing the VF IDs of
the VFs which are required.::
- -w DBDF,representor=[0,1,4]
+ -a DBDF,representor=[0,1,4]
Currently hot-plugging of representor ports is not supported so all required
representors must be specified on the creation of the PF.
