c3dfe188ba examples/vhost: zero copy mode
This patch supports user space vhost zero copy. It removes packets copying between host and guest in RX/TX.
It introduces an extra ring to store the detached mbufs. At initialization stage all mbufs will put into
this ring; when one guest starts, vhost gets the available buffer address allocated by guest for RX and
translates them into host space addresses, then attaches them to mbufs and puts the attached mbufs into
mempool.
Queue starting and DMA refilling will get mbufs from mempool and use them to set the DMA addresses.

For TX, it gets the buffer addresses of available packets to be transmitted from guest and translates
them to host space addresses, then attaches them to mbufs and puts them to TX queues.
After TX finishes, it pulls mbufs out from mempool, detaches them and puts them back into the extra ring.

519f32279e config: rename "default" configurations as "native"
The "default" part in configuration filenames is misleading.
Rename this as "native", as this is the RTE_MACHINE that is set in these files.
This should make it clearer for people who build DPDK on a system then run it on
another one.

e5ffdd1457 ethdev: remove rte_pmd_init_all function
Now that we've converted all the pmds in dpdk to use the driver registration
macro, rte_pmd_init_all has become empty.  As theres no reason to keep it around
anymore, just remove it and fix up all the eample callers.

7b9d82208b ixgbe: convert to use of PMD_REGISTER_DRIVER and fix linking
Convert the ixgbe pmd driver to use the PMD_REGISTER_DRIVER macro.
This means that the test applications now have no reference to the ixgbe library
when building DSO's and must specify its use on the command line with the -d
option.  Static linking will still initalize the driver automatically.

591a9d7985 add FILE argument to debug functions
The DPDK dump functions are useful for remote debugging of an
applications. But when application runs as a daemon, stdout
is typically routed to /dev/null.

Instead change all these functions to take a stdio FILE * handle
instead. An application can then use open_memstream() to capture
the output.

06371afe39 examples/netmap_compat: import netmap compatibility example
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.

4796ad63ba examples/vhost: import userspace vhost application
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.

47bd46112b xen: import xenvirt pmd and vhost_xen
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.
