This vhost example demonstrates how to integrate user space vhost with DPDK
accelerated ethernet vSwitch.
1) rte_vhost_driver_register initialises vhost driver.
2) rte_vhost_driver_callback_register registers new_device/destroy_device
callbacks.
Those callbacks should be implemented in
main.c and main.h are refactored to become vhost lib in vhost lib patch, thus
are removed. Here they are copied back from old vhost example without any
modification.

Old vhost example consists of vhost cuse driver, virtio device management, and
VMDQ based packet switching logic.
vhost cuse driver and virtio device management are moved into vhost lib. This
patch modifies vhost example to use vhost lib API.

Sure, I understand that.
The 7Gb/s performance with iperf that I was getting was with one end-host
using the KNI app and the other host running the traditional linux stack.
With both end hosts running the KNI app, I see about 2.75Gb/s which is
understandable because the

Ah yes, sorry for missing it.
Thanks for correcting and applying, glad to have it available upstream.

The refcnt field is contained within an anonymous union within the mbuf
data structure, and gcc 4.4 gives an error about an unknown field unless
the initialiser for the field is contained within extra braces.

Added 3 new unit tests:
- Functional unit test: Tests creation and handling of
a hash table with a single thread.
- Performance unit tests: Benchmark hash operations
add/delete/lookup, returning number of CPU cycles/operation.
- Multi thread unit tests: Checks there is no data corruption
Added new hash library, as an alternative to the old hash
implementation. This new library allows the user to have
multiple threads reading and writing on the same hash
table at the same time.

rte_prefetchX functions included volatile void *p as parameter,
but the function does not modify it, so it should be const.

This is an alternative hash implementation to the existing hash library.
This patch set provides a thread safe hash implementation, it allows users
to use multiple readers/writers working on a same hash table.
Main differences between the previous and the new implementation are:

Hi,
I've published the source code of Linux kernel IP stack ported to user space
and integrated with DPDK (1.6 currently).
I includes also some example applications & test scripts as well as
documentation
about what & how is done and how to use & adapt it.
