Now that the queue spinlocks have been added to the rx and
tx burst functions the memcpy of the slave data is no
longer necessary, so it has been removed.

At present it is possible to add and remove slave devices from the
bonding device while traffic is running. This can result in
segmentation faults occurring in the rx and tx burst functions.
To resolve this issue spinlocks have been added to the rx and tx
queues.
Now when a slave is added or remov
Add spinlock to bonding rx and tx queues.
Take spinlock in rx and tx burst functions.
Take all spinlocks in slave add and remove functions.
With spinlocks in place remove memcpy of slaves.
Changes in v3:
Rebase to latest master.
Drop patches 4 and 5 from v2 patchset.

Hi Thiago,

Sure. This is the reason: in dpdk-16.04/lib/librte_eal/linuxapp/igb_uio we have:

Compile DPDK with clang, below line in virtio_rxtx.c could be
optimized with four "VMOVAPS ymm, m256".

This instruction requires memory address is 32-byte aligned.
Or, it leads to segfault. Although only tested with Clang 3.6.0,
it can be rep
In ip_pipeline app, the structure app_thread_data needs to be aligned to
the cache line boundary as threads on different cpu cores are accessing
fields of the app->thread_data and having this structure not aligned on
cacheline boundary leads to false cacheline sharing.

Add a new virtual device named vhost-user, which can be used just like
eth_ring, eth_null, etc. To reuse the code of original virtio, we do
some adjustment in virtio_ethdev.c, such as remove key _static_ of

This patch implements another new instance of struct virtio_pci_ops to
drive the virtio-user virtual device. Instead of rd/wr ioport or PCI
configuration space, this virtual pci driver will rd/wr the virtual
device struct virtio_user_hw, and when necessary, invokes APIs provided
by device emulation
Two device emulation layer APIs are added for virtio driver to call:
- virtio_user_start_device()
- virtio_user_stop_device()
- virtio_user_dev_init()
- virtio_user_dev_uninit()
These APIs will get called by virtio driver, and they call vhost adapter
layer APIs to implement the functionali
This patch is to provide vhost adapter layer implementations. Instead

This patch is related to how to calculate relative address for vhost
