+VMWARE vmxnet3 device driver
+============================
+
+##Overview This plugin provides native PCI driver support for VMWare
+vmxnet3.
+
+##Prerequisites \* This code is tested with vfio-pci driver installed
+with Ubuntu 18.04 which has kernel version 4.15.0-33-generic.
+
+-  This driver is tested with ESXi vSwitch version 6.5/6.7 for LRO/TSO
+   support, VMware Workstation 15 Pro (no LRO/TSO), and VMware Fusion 11
+   Pro (no LRO/TSO)
+
+-  Driver requires MSI-X interrupt support, which is not supported by
+   uio_pci_generic driver. So vfio-pci must be used. On systems without
+   IOMMU, vfio driver can still be used with 4.15.0-33-generic kernel
+   (Ubuntu 18.04) which supports no-iommu mode.
+
+##Known issues
+
+-  VLAN filter
+
+Usage
+-----
+
+System setup
+~~~~~~~~~~~~
+
+1. load VFIO driver
+
+::
+
+   sudo modprobe vfio-pci
+
+2. Make sure the interface is down
+
+::
+
+   sudo ifconfig <if-name> down
+
+Steps 3 and 4 are optional. They can be accomplished by specifying the
+optional keyword “bind” when creating the vmxnet3 interface.
+
+3. (systems without IOMMU only) enable unsafe NOIOMMU mode
+
+::
+
+   echo Y | sudo tee /sys/module/vfio/parameters/enable_unsafe_noiommu_mode
+
+4. Bind interface to vfio-pci
+
+::
+
+   sudo dpdk-devbind.py --bind vfio-pci 0b:00.0
+
+Interface Creation
+~~~~~~~~~~~~~~~~~~
+
+Interface can be dynamically created with following CLI, with or without
+the bind option. If step 3 and 4 were executed, bind can be omitted.
+
+::
+
+   create interface vmxnet3 0000:0b:00.0 bind
+   set int state vmxnet3-0/b/0/0 up
+
+Interface Deletion
+~~~~~~~~~~~~~~~~~~
+
+Interface can be deleted with following CLI:
+
+::
+
+   delete interface vmxnet3 <if-name>
+
+Interface Statistics
+~~~~~~~~~~~~~~~~~~~~
+
+Interface statistics can be displayed with
+``show hardware-interface <if-name>`` command.
+
+Show Interface CLI
+~~~~~~~~~~~~~~~~~~
+
+Interface and ring information can be obtained with
+``show vmxnet3 [if-name] [desc]``
