======================
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.
More information can be found at `Chelsio Communications Official Website
<http://www.chelsio.com>`_.
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.
- 40G NICs: T580-CR, T580-LP-CR, T580-SO-CR

-Driver Compilation
-~~~~~~~~~~~~~~~~~~
-
-To compile CXGBE PMD for Linux x86_64 gcc target, run the following "make"
-command:
+- ``CONFIG_RTE_LIBRTE_CXGBE_TPUT`` (default **y**)
-.. code-block:: console
-
- cd <DPDK-source-directory>
- make config T=x86_64-native-linuxapp-gcc install
+ Toggle behaviour to prefer Throughput or Latency.
-To compile CXGBE PMD for FreeBSD x86_64 clang target, run the following "gmake"
-command:
+.. _driver-compilation:
-.. code-block:: console
+Driver compilation and testing
+------------------------------
- cd <DPDK-source-directory>
