I got many warnings at the link step with gcc version 5.3.1 20160225 (Ubuntu 5.3.1-10ubuntu2):

Looking at vlib_node_registration_t, I think the reason is that
the char * next_nodes[] could be bigger where the variable is defined
in .c file.
We should mark global variables as external in header files.
Some of them can be made static.

In case socket-mem was set to <1024 and no 1G page long hupepages were
available, the condition was evaluated in unexpected manner. In other
words use_1g == 1, and that fails later in mount().
This patch makes sure this is prevented - if there are no pages_available,
do not even try to use that pagesize.

So unless I have missed something, loopback interfaces
are spawned hardware-down and never set up. This patch
uses the same process as tapcli interfaces by

Both ARP and NDP need to be called when hi->output_node_index is changed.
It does not look like a perfect solution though. Maybe an actual up-down

It turns out that unix_physmem_init(...) has been effectively disabled
for a very long time. The vnet library supplied a weak symbol override
for the vlib_app_physmem_init(...) which returned 1, meaning "do
nothing." When we switched libvnet.a -> libvnet.so, the symbol
override stopped working.
Presto: unix_physmem_init(...) romps all over the data set up by
vlib_buffer_pool_create(...), leading to ASSERT failures and/or bus
errors, but only when using worker threads. Even then, the failure
depended in some complicated way on library dynamic load order.
We should remove .../vlib/vlib/unix/physmem.c entirely once we're sure
we'll never want it back.

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, ยง "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.

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.

If system have more worker threads than TX queues they will

Also, provide vlib's dpdk configuration function so that plugins that

that dpdk itself is initialized first.
