fields.

Struct vhost_virtqueue is reserved with 16 qwords (the later vhost-live
migration support would at least consume 3 of them), and struct virtio_net
is reserved with a bit more, 64 qwords, as there is only one instance for
a virtio nic instance.

Note that both reservation are not placed at the end of the struct, but
instead before the last field, since both the last field at the two struct
take a lot spaces. Putting the reservation after it would divide those
reserved fields to another cacheline. (we might need fix them in future, btw)

examples/ip_pipeline: add missing files of flow actions pipeline

When first adding flow actions pipeline, some files were not pushed
to the repository by mistake. The original commit message is below.

Fixes: 9ef2593651f9 ("examples/ip_pipeline: add flow actions pipeline")

Flow actions pipeline is an extension of flow-classification pipeline.
Some of the operations of flow classification pipeline such as traffic
metering/marking(for e.g. Single Rate Three Color Marker (srTCM), Two
Rate Three Color Marker trTCM)), policer can be performed separately in
flow action pipeline to avoid excessive computational burden on the CPU
core running the flow-classification pipeline. The Flow action pipeline
implements various function such as traffic metering, policer, stats.
Traffic mettering can configured as per the required context, for
examples- per user, per traffic class or both. These contexts can be
applied by specifying parameters in configuration file as shown below;

[PIPELINE1]
type = FLOW_ACTIONS
core = 1
pktq_in = RXQ0.0 RXQ1.0 RXQ2.0 RXQ3.0
pktq_out = TXQ0.0 TXQ1.0 TXQ2.0 TXQ3.0
n_flows = 65536
n_meters_per_flow = 1
flow_id_offset = 158
ip_hdr_offset = 142
color_offset = 64

The entries of flow and dscp tables of flow actions pipeline can be
modified through command-line interface. The commands to add or delete
entries to the flow table, DSCP(differentiated services code point)
table and for statistics collection, etc have been included. The key
functions such as Traffic Metering/marking and policer functions have
been implemented as flow-table action handler.

app/test: fix ring unit test

If eth_ring vdevs are created from the command line with the --vdev option,
they create their own rings which are not shared by other vdevs.
Some of tests in this suite require that the vdevs share rings, so some
of the tests fail.

For vdevs to share rings they must be created in the test code with the
rte_eth_from_rings() function using rings created with the rte_ring_create()
function.

Use the command line option --vdev=eth_ring0 to create port 0.
This option is not mandatory for the tests to pass. It allows some additional
functional tests on cmd-line created rings to be executed.

Create two rings and five ethdevs in test_pmd_ring.c for ports 1 to 5,
and then use these to run the unit tests on the pmd ring functionality.

Improve test output by adding the port number to printf statements,
and adding a printf describing each test.

examples/l3fwd: fix crash with unaligned L2 header

l3fwd app expects PMDs to return packets whose L2 header is
16-byte aligned due to usage of _mm_load_si128()/_mm_store_si128()
intrinsics in the app. However, most of the protocol stacks expects
packets such that its IP/L3 header be aligned on a 16-byte boundary.

Based on the recommendations received on dpdk-dev, we are changing
the l3fwd app to use _mm_loadu_si128()/_mm_loadu_si128() so that the
address need not be 16-byte aligned and thereby preventing crash.
