'fec-uio' is the UIO driver, ENETFEC PMD\n+uses UIO interface to interact with kernel for PHY initialisation and for mapping\n+the allocated memory of register & BD in kernel with DPDK which gives access to\n+non-cacheable memory for BD. net_enetfec is logical Ethernet interface, created by\n+ENETFEC driver.\n+\n+- ENETFEC driver registers the device in virtual device driver.\n+- RTE framework scans and will invoke the probe function of ENETFEC 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 via logical interfaces.\n+\n+ENETFEC Features\n+~~~~~~~~~~~~~~~~~\n+\n+- ARMv8\n+\n+Supported ENETFEC SoCs\n+~~~~~~~~~~~~~~~~~~~~~~\n+\n+- i.MX 8M Mini\n+\n+Prerequisites\n+~~~~~~~~~~~~~\n+\n+There are three main pre-requisites for executing ENETFEC PMD on a i.MX 8M Mini\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/7.4-2019.02/aarch64-linux-gnu/gcc-linaro-7.4.1-2019.02-x86_64_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 18.04 LTS (Bionic) or 20.04 LTS(Focal) 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+4. The Ethernet device will be registered as virtual device, so ENETFEC has dependency on\n+ **rte_bus_vdev** library and it is mandatory to use `--vdev` with value `net_enetfec` to\n+ run DPDK application.\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+Limitations\n+~~~~~~~~~~~\n+\n+- Multi queue is not supported.\n+- Link status is down always.\n+- Single Ethernet interface.\ndiff --git a/doc/guides/nics/features/enetfec.ini b/doc/guides/nics/features/enetfec.ini\nnew file mode 100644\nindex 0000000000..5700697981\n--- /dev/null\n+++ b/doc/guides/nics/features/enetfec.ini\n@@ -0,0 +1,8 @@\n+;\n+; Supported features of the 'enetfec' network poll mode driver.\n+;\n+; Refer to default.ini for the full list of available PMD features.\n+;\n+[Features]\n+ARMv8 = Y\n+Usage doc = Y\ndiff --git a/doc/guides/nics/index.rst b/doc/guides/nics/index.rst\nindex 784d5d39f6..777fdab4a0 100644\n--- a/doc/guides/nics/index.rst\n+++ b/doc/guides/nics/index.rst\n@@ -26,6 +26,7 @@ Network Interface Controller Drivers\n e1000em\n ena\n enetc\n+ enetfec\n enic\n fm10k\n hinic\ndiff --git a/drivers/net/enetfec/enet_ethdev.c b/drivers/net/enetfec/enet_ethdev.c\nnew file mode 100644\nindex 0000000000..88774788cf\n--- /dev/null\n+++ b/drivers/net/enetfec/enet_ethdev.c\n@@ -0,0 +1,95 @@\n+/* SPDX-License-Identifier: BSD-3-Clause\n+ * Copyright 2020-2021 NXP\n+ */\n+\n+#include <stdio.h>\n+#include <fcntl.h>\n+#include <stdlib.h>\n+#include <unistd.h>\n+#include <errno.h>\n+#include <rte_kvargs.h>\n+#include <ethdev_vdev.h>\n+#include <rte_bus_vdev.h>\n+#include <rte_dev.h>\n+#include <rte_ether.h>\n+#include \"enet_ethdev.h\"\n+#include \"enet_pmd_logs.h\"\n+\n+#define ENETFEC_NAME_PMD net_enetfec\n+#define ENETFEC_VDEV_GEM_ID_ARG \"intf\"\n+#define ENETFEC_CDEV_INVALID_FD -1\n+\n+int enetfec_logtype_pmd;\n+\n+static int\n+enetfec_eth_init(struct rte_eth_dev *dev)\n+{\n+\trte_eth_dev_probing_finish(dev);\n+\treturn 0;\n+}\n+\n+static int\n+pmd_enetfec_probe(struct rte_vdev_device *vdev)\n+{\n+\tstruct rte_eth_dev *dev = NULL;\n+\tstruct enetfec_private *fep;\n+\tconst char *name;\n+\tint rc;\n+\n+\tname = rte_vdev_device_name(vdev);\n+\tif (name == NULL)\n+\t\treturn -EINVAL;\n+\tENETFEC_PMD_LOG(INFO, \"Initializing pmd_fec for %s\", name);\n+\n+\tdev = rte_eth_vdev_allocate(vdev, sizeof(*fep));\n+\tif (dev == NULL)\n+\t\treturn -ENOMEM;\n+\n+\t/* setup board info structure */\n+\tfep = dev->data->dev_private;\n+\tfep->dev = dev;\n+\trc = enetfec_eth_init(dev);\n+\tif (rc)\n+\t\tgoto failed_init;\n+\n+\treturn 0;\n+\n+failed_init:\n+\tENETFEC_PMD_ERR(\"Failed to init\");\n+\treturn rc;\n+}\n+\n+static int\n+pmd_enetfec_remove(struct rte_vdev_device *vdev)\n+{\n+\tstruct rte_eth_dev *eth_dev = NULL;\n+\tint ret;\n+\n+\t/* find the ethdev entry */\n+\teth_dev = rte_eth_dev_allocated(rte_vdev_device_name(vdev));\n+\tif (eth_dev == NULL)\n+\t\treturn -ENODEV;\n+\n+\tret = rte_eth_dev_release_port(eth_dev);\n+\tif (ret != 0)\n+\t\treturn -EINVAL;\n+\n+\tENETFEC_PMD_INFO(\"Closing sw device\");\n+\treturn 0;\n+}\n+\n+static struct rte_vdev_driver pmd_enetfec_drv = {\n+\t.probe = pmd_enetfec_probe,\n+\t.remove = pmd_enetfec_remove,\n+};\n+\n+RTE_PMD_REGISTER_VDEV(ENETFEC_NAME_PMD, pmd_enetfec_drv);\n+RTE_PMD_REGISTER_PARAM_STRING(ENETFEC_NAME_PMD, ENETFEC_VDEV_GEM_ID_ARG \"=<int>\");\n+\n+RTE_INIT(enetfec_pmd_init_log)\n+{\n+\tint ret;\n+\tret = rte_log_register_type_and_pick_level(ENETFEC_LOGTYPE_PREFIX \"driver\",\n+\t\t\t\t\t\t RTE_LOG_NOTICE);\n+\tenetfec_logtype_pmd = (ret < 0) ?
