poll mode driver library. The bonded interfaces to be created on
VPP startup is specified in the dpdk section of startup.conf
or qn.conf, using DPDK EAL command. Following is an example of a
dpdk section white listing PCI addressses of 4 ethernet interfacess
to be under VPP control plus two bonded interface and the PCI addresses
of the slaves in each:
dpdk { socket-mem 1024,1024
dev 0000:0f:00.0 dev 0000:10:00.0 dev 0000:11:00.0 dev 0000:12:00.0
vdev eth_bond0,mode=2,slave=0000:0f:00.0,slave=0000:11:00.0,xmit_policy=l34
vdev eth_bond1,mode=2,slave=0000:10:00.0,slave=0000:12:00.0,xmit_policy=l34
}
Note that only balance XOR (mode 2) is supported and "xmit_policy=l34"
specifies to use layer 3 SIP/DIP and layer 4 Sport/Dport for load
balance. Using "xmit_policy=l2" for SMAC/DMAC or "xmit_policy=l23" for
SMAC/DMAC and SIP/DIP should also work.

This patch adds live migration support to vhost interfaces, by supporting the VHOST_F_LOG_ALL feature. When qemu starts a migration, it will negotiate this feature, and provide a fd for a "dirty log" shared mem space. This log is a bitmap representing pages in the device memory.
Whenever we touch memory pointed by a "desc" vring, or modify a "used" vring, we log the corresponding page in the bitmap. This allows qemu to send the dirty page to the destination host.
See https://github.com/qemu/qemu/blob/master/docs/specs/vhost-user.txt, § "Live migration" for more details.
In addition to this, this code provides support for the VHOST_USER_F_PROTOCOL_FEATURES feature, and to VHOST_USER_{GET,SET}_PROTOCOL_FEATURES and VHOST_USER_SET_VRING_ENABLE messages, required for live migration.

If number of Qs enabled by the guest is less
than number of Qs exported to guest, then all
threads route packet to Q0 with the assumption
that guest is not interested in performance.
If all Qs are enabled, each thread queues packet
in their own TX-Q of the VHOST_USER interface,
boosting performance.

Adding a patch to fix DPDK 2.2.0 enic PMD driver TX function.
The enic PMD driver send function uses a constant offset instead of relying on the data_off in the mbuf to find the start of the packet.

AtomicBoolean forces the enclosed boolean to be cache-aligned,
needlessly hitting a cacheline. Since we only flip state only once,
when the connection is severed, we can turn this into a volatile
boolean.
Doing that is costing us a synchronized close(), but that is perfectly
acceptable, as that is called only once.

This code provided inter-VM (2 cores per VM) throughput of
22Gbps using iperf through VPP (1 core) with 9k frames.
With the same setup and pktgen running on both sides, it
reached 5Mpps with no packets drop (Equivalent to before the patch).
During the tests the average vector length was about 1, which
likely means that VPP is not the bottleneck.
The patch also includes some generic functions for vlib buffers
allowing for chained buffer construction whether or not DPDK is enabled.

on non-dpdk paravirtualized interfaces, and packets originating in the

If system have more worker threads than TX queues they will
