This provides a sample application and library showing how to use the
Intel(R) DPDK with basic netmap applications.
The Netmap compatibility library provides a minimal set of APIs to give the ability to
programs written against the Netmap APIs to be run with minimal changes to their
source code, using the Intel® DPDK to perform the actual packet I/O.
Since Netmap applications use regular system calls, like open(), ioctl() and
mmap() to communicate with the Netmap kernel module performing the packet I/O,
the compat_netmap library provides a set of similar APIs to use in place of those
system calls, effectively turning a Netmap application into a Intel(R) DPDK one.
The provided library is currently minimal and doesn’t support all the features that
Netmap supports, but is enough to run simple applications, such as the
bridge example included.
The application requires a single command line option:
-i INTERFACE is the number of a valid Intel(R) DPDK port to use.
If a single -i parameter is given, the interface will send back all the traffic it
receives. If two -i parameters are given, the two interfaces form a bridge, where
traffic received on one interface is replicated and sent by the other interface.

This provides a new sample application which demonstrates how
the ivshmem library and EAL capabilities can be used to create
a zero-copy fast-path for packet communication between host
machine and guest vm.

The vhost sample application demonstrates integration of the Intel(R) Data Plane
Development Kit (Intel(R) DPDK) with the Linux KVM hypervisor by implementing the
vhost-net offload API. The sample application performs simple packet switching
between virtual machines based on Media Access Control (MAC) address or Virtual
Local Area Network (VLAN) tag. The splitting of ethernet traffic from an external switch
is performed in hardware by the Virtual Machine Device Queues (VMDQ) and Data
Center Bridging (DCB) features of the Intel(R) 82599 10 Gigabit Ethernet Controller.

This provides a para-virtualization packet switching solution, based on the
Xen hypervisor’s Grant Table, which provides simple and fast packet
switching capability between guest domains and host domain based on
MAC address or VLAN tag.
This solution is comprised of two components; a Poll Mode Driver (PMD)
as the front end in the guest domain and a switching back end in the
host domain. XenStore is used to exchange configure information
between the PMD front end and switching back end,
including grant reference IDs for shared Virtio RX/TX rings, MAC
address, device state, and so on.
The front end PMD can be found in the Intel DPDK directory lib/
librte_pmd_xenvirt and back end example in examples/vhost_xen.

Core support for using the Intel DPDK with Xen Dom0 - including EAL
changes and mempool changes. These changes encompass how memory mapping
is done, including support for initializing a memory pool inside an
already-allocated block of memory.
KNI sample app updated to use KNI close function when used with Xen.
