CXGBE Poll Mode Driver
======================
The CXGBE PMD (**librte_pmd_cxgbe**) provides poll mode driver support
-for **Chelsio T5** 10/40 Gbps family of adapters. CXGBE PMD has support
-for the latest Linux and FreeBSD operating systems.
+for **Chelsio Terminator** 10/25/40/100 Gbps family of adapters. CXGBE PMD
+has support for the latest Linux and FreeBSD operating systems.
+
+CXGBEVF PMD provides poll mode driver support for SR-IOV Virtual functions
+and has support for the latest Linux operating systems.
More information can be found at `Chelsio Communications Official Website
<http://www.chelsio.com>`_.
Features
--------
-CXGBE PMD has support for:
+CXGBE and CXGBEVF PMD has support for:
- Multiple queues for TX and RX
- Receiver Side Steering (RSS)
+ Receiver Side Steering (RSS) on IPv4, IPv6, IPv4-TCP/UDP, IPv6-TCP/UDP.
+ For 4-tuple, enabling 'RSS on TCP' and 'RSS on TCP + UDP' is supported.
- VLAN filtering
- Checksum offload
- Promiscuous mode
- All multicast mode
- Port hardware statistics
- Jumbo frames
+- Flow API - Support for both Wildcard (LE-TCAM) and Exact (HASH) match filters.
Limitations
-----------
-The Chelsio T5 devices provide two/four ports but expose a single PCI bus
-address, thus, librte_pmd_cxgbe registers itself as a
-PCI driver that allocates one Ethernet device per detected port.
+The Chelsio Terminator series of devices provide two/four ports but
+expose a single PCI bus address, thus, librte_pmd_cxgbe registers
+itself as a PCI driver that allocates one Ethernet device per detected
+port.
For this reason, one cannot whitelist/blacklist a single port without
whitelisting/blacklisting the other ports on the same device.

+
+Supported SR-IOV Chelsio NICs
+-----------------------------
+
+SR-IOV virtual functions are supported on all the Chelsio NICs listed
+in :ref:`t5-nics` and :ref:`t6-nics`.
+
Prerequisites
-------------
-- Requires firmware version **1.13.32.0** and higher. Visit
+- Requires firmware version **1.24.11.0** and higher. Visit
`Chelsio Download Center <http://service.chelsio.com>`_ to get latest firmware
bundled with the latest Chelsio Unified Wire package.
Toggle compilation of librte_pmd_cxgbe driver.
-- ``CONFIG_RTE_LIBRTE_CXGBE_DEBUG`` (default **n**)
+ .. note::
- Toggle display of generic debugging messages.
+ This controls compilation of both CXGBE and CXGBEVF PMD.
-- ``CONFIG_RTE_LIBRTE_CXGBE_DEBUG_REG`` (default **n**)
+Runtime Options
+~~~~~~~~~~~~~~~
- Toggle display of registers related run-time check messages.
+The following ``devargs`` options can be enabled at runtime. They must
+be passed as part of EAL arguments. For example,
-- ``CONFIG_RTE_LIBRTE_CXGBE_DEBUG_MBOX`` (default **n**)
+.. code-block:: console
- Toggle display of firmware mailbox related run-time check messages.
+ testpmd -w 02:00.4,keep_ovlan=1 -- -i
+
+Common Runtime Options
+^^^^^^^^^^^^^^^^^^^^^^
+
+- ``keep_ovlan`` (default **0**)
+
+ Toggle behavior to keep/strip outer VLAN in Q-in-Q packets. If
+ enabled, the outer VLAN tag is preserved in Q-in-Q packets. Otherwise,
+ the outer VLAN tag is stripped in Q-in-Q packets.
+
+- ``tx_mode_latency`` (default **0**)
+
+ When set to 1, Tx doesn't wait for max number of packets to get
+ coalesced and sends the packets immediately at the end of the
+ current Tx burst. When set to 0, Tx waits across multiple Tx bursts
+ until the max number of packets have been coalesced. In this case,
+ Tx only sends the coalesced packets to hardware once the max
+ coalesce limit has been reached.
+
+CXGBE VF Only Runtime Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- ``force_link_up`` (default **0**)
+
+ When set to 1, CXGBEVF PMD always forces link as up for all VFs on
+ underlying Chelsio NICs. This enables multiple VFs on the same NIC
+ to send traffic to each other even when the physical link is down.
+
+CXGBE PF Only Runtime Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- ``filtermode`` (default **0**)
+
+ Apart from the 4-tuple (IP src/dst addresses and TCP/UDP src/dst port
+ addresses), there are only 40-bits available to match other fields in
+ packet headers. So, ``filtermode`` devarg allows user to dynamically
+ select a 40-bit supported match field combination for LETCAM (wildcard)
+ filters.
+
+ Default value of **0** makes driver pick the combination configured in
+ the firmware configuration file on the adapter.
+
+ The supported flags and their corresponding values are shown in table below.
+ These flags can be OR'd to create 1 of the multiple supported combinations
+ for LETCAM filters.

+
+ For example, to enable matching ``ethertype`` field in Ethernet
+ header, and ``protocol`` field in IPv4 header, the ``filtermode``
+ combination must be given as:
-- ``CONFIG_RTE_LIBRTE_CXGBE_DEBUG_TX`` (default **n**)
+ .. code-block:: console
- Toggle display of transmission data path run-time check messages.
+ testpmd -w 02:00.4,filtermode=0x88 -- -i
-- ``CONFIG_RTE_LIBRTE_CXGBE_DEBUG_RX`` (default **n**)
+- ``filtermask`` (default **0**)
- Toggle display of receiving data path run-time check messages.
+ ``filtermask`` devarg works similar to ``filtermode``, but is used
+ to configure a filter mode combination for HASH (exact-match) filters.
-.. _driver-compilation:
+ .. note::
-Driver Compilation
-~~~~~~~~~~~~~~~~~~
+ The combination chosen for ``filtermask`` devarg **must be a subset** of
+ the combination chosen for ``filtermode`` devarg.
-To compile CXGBE PMD for Linux x86_64 gcc target, run the following "make"
-command:
+ Default value of **0** makes driver pick the combination configured in
+ the firmware configuration file on the adapter.
-.. code-block:: console
+ Note that the filter rule will only be inserted in HASH region, if the
+ rule contains **all** the fields specified in the ``filtermask`` combination.
+ Otherwise, the filter rule will get inserted in LETCAM region.
- cd <DPDK-source-directory>
- make config T=x86_64-native-linuxapp-gcc install
+ The same combination list explained in the tables in ``filtermode`` devarg
+ section earlier applies for ``filtermask`` devarg, as well.
-To compile CXGBE PMD for FreeBSD x86_64 clang target, run the following "gmake"
-command:
+ For example, to enable matching only protocol field in IPv4 header, the
+ ``filtermask`` combination must be given as:
-.. code-block:: console
+ .. code-block:: console
+
+ testpmd -w 02:00.4,filtermode=0x88,filtermask=0x80 -- -i
