IEP implements\n+peripheral devices in an SoC such that software sees them as PCIe device.\n+ENETC is an evolution of BDR(Buffer Descriptor Ring) based networking\n+IPs.\n+\n+This infrastructure simplifies adding support for IEP and facilitates in following:\n+\n+- Device discovery and location\n+- Resource requirement discovery and allocation (e.g. interrupt assignment,\n+ device register address)\n+- Event reporting\n+\n+ENETC Features\n+~~~~~~~~~~~~~~\n+\n+- Link Status\n+- Packet type information\n+\n+NIC Driver (PMD)\n+~~~~~~~~~~~~~~~~\n+\n+ENETC PMD is traditional DPDK PMD which provides necessary interface between\n+RTE framework and ENETC internal drivers.\n+\n+- Driver registers the device vendor table in PCI subsystem.\n+- RTE framework scans the PCI bus for connected devices.\n+- This scanning will invoke the probe function of ENETC driver.\n+- The probe function will set the basic device registers and also setups BD rings.\n+- On packet Rx the respective BD Ring status bit is set which is then used for\n+ packet processing.\n+- Then Tx is done first followed by Rx.\n+\n+Supported ENETC SoCs\n+~~~~~~~~~~~~~~~~~~~~\n+\n+- LS1028\n+\n+Prerequisites\n+~~~~~~~~~~~~~\n+\n+There are three main pre-requisities for executing ENETC PMD on a ENETC\n+compatible board:\n+\n+1. **ARM 64 Tool Chain**\n+\n+ For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/aarch64-linux-gnu/gcc-linaro-7.3.1-2018.05-i686_aarch64-linux-gnu.tar.xz>`_.\n+\n+2. **Linux Kernel**\n+\n+ It can be obtained from `NXP's Github hosting <https://source.codeaurora.org/external/qoriq/qoriq-components/linux>`_.\n+\n+3. **Rootfile system**\n+\n+ Any *aarch64* supporting filesystem can be used. For example,\n+ Ubuntu 16.04 LTS (Xenial) or 18.04 (Bionic) userland which can be obtained\n+ from `here <http://cdimage.ubuntu.com/ubuntu-base/releases/18.04/release/ubuntu-base-18.04.1-base-arm64.tar.gz>`_.\n+\n+The following dependencies are not part of DPDK and must be installed\n+separately:\n+\n+- **NXP Linux LSDK**\n+\n+ NXP Layerscape software development kit (LSDK) includes support for family\n+ of QorIQ® ARM-Architecture-based system on chip (SoC) processors\n+ and corresponding boards.\n+\n+ It includes the Linux board support packages (BSPs) for NXP SoCs,\n+ a fully operational tool chain, kernel and board specific modules.\n+\n+ LSDK and related information can be obtained from: `LSDK <https://www.nxp.com/support/developer-resources/run-time-software/linux-software-and-development-tools/layerscape-software-development-kit:LAYERSCAPE-SDK>`_\n+\n+Driver compilation and testing\n+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n+\n+Follow instructions available in the document\n+:ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`\n+to launch **testpmd**\n+\n+To compile in performance mode, please set ``CONFIG_RTE_CACHE_LINE_SIZE=64``\ndiff --git a/doc/guides/nics/features/enetc.ini b/doc/guides/nics/features/enetc.ini\nnew file mode 100644\nindex 000000000..69476a2a1\n--- /dev/null\n+++ b/doc/guides/nics/features/enetc.ini\n@@ -0,0 +1,11 @@\n+;\n+; Supported features of the 'enetc' network poll mode driver.\n+;\n+; Refer to default.ini for the full list of available PMD features.\n+;\n+[Features]\n+Packet type parsing = Y\n+Link status = Y\n+Linux VFIO = Y\n+ARMv8 = Y\n+Usage doc = Y\ndiff --git a/doc/guides/nics/index.rst b/doc/guides/nics/index.rst\nindex 59f6063dc..0323035d3 100644\n--- a/doc/guides/nics/index.rst\n+++ b/doc/guides/nics/index.rst\n@@ -21,6 +21,7 @@ Network Interface Controller Drivers\n dpaa2\n e1000em\n ena\n+ enetc\n enic\n fm10k\n i40e\ndiff --git a/doc/guides/rel_notes/release_18_11.rst b/doc/guides/rel_notes/release_18_11.rst\nindex 3ae6b3f58..f4a2535f4 100644\n--- a/doc/guides/rel_notes/release_18_11.rst\n+++ b/doc/guides/rel_notes/release_18_11.rst\n@@ -50,6 +50,11 @@ New Features\n * Other libs\n * Apps, Examples, Tools (if significative)\n \n+ * **Added NXP ENETC PMD.**\n+\n+ Added the new enetc driver for NXP enetc platform.
