meter: add configuration profile

This patch adds support for meter configuration profiles.
Benefits: simplified configuration procedure, improved performance.

Q1: What is the configuration profile and why does it make sense?
A1: The configuration profile represents the set of configuration
    parameters for a given meter object, such as the rates and sizes for
    the token buckets. The configuration profile concept makes sense when
    many meter objects share the same configuration, which is the typical
    usage model: thousands of traffic flows are each individually metered
    according to just a few service levels (i.e. profiles).

Q2: How is the configuration profile improving the performance?
A2: The performance improvement is achieved by reducing the memory
    footprint of a meter object, which results in better cache utilization
    for the typical case when large arrays of meter objects are used. The
    internal data structures stored for each meter object contain:
       a) Constant fields: Low level translation of the configuration
          parameters that does not change post-configuration. This is
          really duplicated for all meters that use the same
          configuration. This is the configuration profile data that is
          moved away from the meter object. Current size (implementation
          dependent): srTCM = 32 bytes, trTCM = 32 bytes.
       b) Variable fields: Time stamps and running counters that change
          during the on-going traffic metering process. Current size
          (implementation dependent): srTCM = 24 bytes, trTCM = 32 bytes.
          Therefore, by moving the constant fields to a separate profile
          data structure shared by all the meters with the same
          configuration, the size of the meter object is reduced by ~50%.

PMD: Kernel refused TC filter rule creation (17): File exists

Root cause analysis: during the execution of "port start all" command
testpmd calls rte_eth_promiscuous_enable() while during the execution
of "port stop all" command testpmd does not call
rte_eth_promiscuous_disable().
As a result the TAP PMD is trying to add tc (traffic control command)
promiscuous rules to the remote netvsc device consecutively. From the
kernel point of view it is seen as an attempt to add the same rule more
than once. In recent kernels (e.g. version 4.13) this attempt is rejected
with a "File exists" error. In less recent kernels (e.g. version 4.4) the
same rule may have been successfully accepted twice, which is undesirable.

In the corrupted code every tc promiscuous rule included a different
handle number parameter. If instead an identical handle number is
used for all tc promiscuous rules - all kernels will reject the second
identical rule with a "File exists" error, which is easy to identify and

net/virtio: fix resuming port with Rx vector path

Since commit efc83a1e7fc3 ("net/virtio: fix queue setup consistency"),
when resuming a virtio port, the rx rings are refilled with new mbufs
until they are full (vq->vq_free_cnt == 0). This is done without
ensuring that the descriptor index remains a multiple of
RTE_VIRTIO_VPMD_RX_REARM_THRESH, which is a prerequisite when using the
vector mode. This can cause an out of bound access in the rx ring.

This commit changes the vector refill method from
virtqueue_enqueue_recv_refill_simple() to virtio_rxq_rearm_vec(), which
properly checks that the refill is done by batch of
RTE_VIRTIO_VPMD_RX_REARM_THRESH.

As virtqueue_enqueue_recv_refill_simple() is no more used, this
patch also removes the function.

When the sub-device arguments successfully was parsed, the state is
raised from DEV_UNDEFINED to DEV_PARSED.
When the sub-device successfully was probed, the state is raised from

When the sub-device successfully was started by rte_eth_dev_start(), the
state is raised from DEV_ACTIVE to DEV_STARTED.

When the sub-device successfully was stopped by rte_eth_dev_stop(), the

When the sub-device successfully was closed by rte_eth_dev_close(), the

because the application triggered dev_stop() operation cannot be
reconfigured again by dev_configure() operation which is really
problematic when application wants to reconfigure its ports.

net/failsafe: fix hotplug races

Fail-safe uses a periodic alarm mechanism, running from the host
thread, to manage the hot-plug events of its sub-devices. This
management requires a lot of sub-devices PMDs operations
(stop, close, start, configure, etc.).

While the hot-plug alarm runs in the host thread, the application may
call fail-safe operations, which directly trigger the sub-devices PMDs
operations as well. This call may occur from any thread decided by the
application (probably the master thread).

Thus, more than one operation can be executed to a sub-device at the
same time. This can initiate a lot of races in the sub-PMDs.

Moreover, some control operations update the fail-safe internal
databases, which can be used by the alarm mechanism at the same time.
This can also initiate races and crashes.

Fail-safe is the owner of its sub-devices and must synchronize their
use according to the ETHDEV ownership rules.

Synchronize hot-plug management by a new lock mechanism uses a mutex to
atomically defend each critical section in the fail-safe hot-plug
mechanism and control operations to prevent any races between them.

whether its software resources should be released.

This flag is set when the fail-safe receives an RMV notification
