+AVP Poll Mode Driver
+=================================================================
+
+The Accelerated Virtual Port (AVP) device is a shared memory based device
+available on the `virtualization platforms <http://www.windriver.com/products/titanium-cloud/>`_
+from Wind River Systems.  It is based on an earlier implementation of the DPDK
+KNI device and made available to VM instances via a mechanism based on an early
+implementation of qemu-kvm ivshmem.
+
+The driver binds to PCI devices that are exported by the hypervisor DPDK
+application via the ivshmem-like mechanism.  The definition of the device
+structure and configuration options are defined in rte_avp_common.h and
+rte_avp_fifo.h.  These two header files are made available as part of the PMD
+implementation in order to share the device definitions between the guest
+implementation (i.e., the PMD) and the host implementation (i.e., the
+hypervisor DPDK application).
+
+
+Features and Limitations of the AVP PMD
+---------------------------------------
+
+The AVP PMD driver provides the following functionality.
+
+*   Receive and transmit of both simple and chained mbuf packets,
+
+*   Chained mbufs may include up to 5 chained segments,
+
+*   Up to 8 receive and transmit queues per device,
+
+*   Only a single MAC address is supported,
+
+*   The MAC address cannot be modified,
+
+*   The maximum receive packet length is 9238 bytes,
+
+*   VLAN header stripping and inserting,
+
+*   Promiscuous mode
+
+*   VM live-migration
+
+*   PCI hotplug insertion and removal
+
+
+Prerequisites
+-------------
+
+The following prerequisites apply:
+
+*   A virtual machine running in a Wind River Systems virtualization
+    environment and configured with at least one neutron port defined with a
+    vif-model set to "avp".
+
+
+Launching a VM with an AVP type network attachment
+--------------------------------------------------
+
+The following example will launch a VM with three network attachments.  The
+first attachment will have a default vif-model of "virtio".  The next two
+network attachments will have a vif-model of "avp" and may be used with a DPDK
+application which is built to include the AVP PMD driver.
