Signed-off-by: Bruce Richardson <bruce.richardson@intel.com>

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%.

net/failsafe: fix Rx interrupt reinstallation

Fail-safe dev_start() operation can be called by both the application
and the hot-plug alarm mechanism.

The installation of Rx interrupt are triggered from dev_start() in any
time it is called while actually the Rx interrupt should be installed
only by the application calls.

So, each plug-in event causes reinstallation which causes memory leak
and spoils the fail-safe Rx interrupt mechanism.

Trigger the Rx interrupt installation only when it does not exist.

net/tap: fix promiscuous rules double insertions

Running testpmd command "port stop all" followed by command "port start
all" may result in a TAP error:
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
to silently ignore.

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

net/failsafe: fix reconfiguration

Fail-safe PMD manages the states of its sub-devices gradually:
DEV_UNDEFINED, DEV_PARSED, DEV_PROBED, DEV_ACTIVE, DEV_STARTED.

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
DEV_PARSED to DEV_PROBED.
When the sub-device successfully was configured by
rte_eth_dev_configure(), the state is raised from DEV_PROBED to
DEV_ACTIVE.
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
state is degraded from DEV_STARTED to DEV_ACTIVE.
When the sub-device successfully was closed by rte_eth_dev_close(), the
state is degraded from DEV_ACTIVE to DEV_PROBED.
When the sub-device successfully was removed by
rte_eal_hotplug_remove(), the state is degraded from DEV_PROBED to
DEV_UNDEFINED.

Fail-safe dev_configure() operation calls to its sub-devices
dev_configure() operation, but only for sub-devices which are in
DEV_PROBED state, means that sub-devices which are in DEV_ACTIVE state
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.
Actually, the application may get success report when some of the
sub-devices are not in the wanted configuration.

The current behavior of fail-safe dev_configure() is correct only for
the first time dev_configure() is triggered by the application or for
sub-device synchronization in plug-in event, but it ignores the option
for reconfiguration from application side.

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.

net/failsafe: fix removal scope

The fail-safe PMD uses a per sub-device flag called "remove" to
indicate the scope where the sub-device was removed physically and
whether its software resources should be released.

This flag is set when the fail-safe receives an RMV notification
about the physical removal of the sub-device, and should be unset when
all the sub-device resources are released.

The previous code wrongly unsets the flag in dev_configure(), instead
of when the software resources release is completed.

Change the remove flag unsetting to take action in the end of the

net/failsafe: fix hotplug alarm cancel

handling removed devices during a plug-out event and to restore them
back to activity following a plug-in event.

Fail-safe sets a flag called "pending_alarm" to validate that only one
alarm callback is pending at any time. While this flag is required to
avoid simultaneous initiations of the alarm thread - it should not be
considered during alarm thread cancellation.

So, when failsafe_hotplug_alarm_cancel() was called while the alarm
callback was being executed the alarm mechanism was not stopped.

Skip checking the "pending_alarm" flag to allow alarm thread

ethdev: fix data alignment

The struct rte_eth_dev_data is used in ethdev fastpath routines
and it not aligned to cache line size. This patch fixes the ethdev
data alignment.

The alignment was broken from the "first public release" changeset
where ethdev data address was aligned only to the first port.
Remaining ports alignment was defined by the size of the struct
(rte_eth_dev_data). This scheme is not guaranteed to be cache line
aligned all the time.

"ethdev: add port ownership" change set introduced a
rte_eth_dev_shared_data container for port ownership change,
This resulted in rte_eth_dev->data memory for the first port also
as cache unaligned.

Added a compiler alignment attribute to make sure
rte_eth_dev->data always cache aligned so that CPU/compiler
1) Avoid sharing the element with another cache line
2) Can load/store the elements in struct rte_eth_dev_data as
naturally aligned.

buildtools: output build failure reason to stderr

If build fails because of failed experimental check and stdout is
redirected to /dev/null, it is absolutely unclear why build fails.

eal/ppc64: revert arch-specific TSC freq query

This reverts commit 15692396fd68932b6a81f00f12d4b0da12baa7d3
(eal/ppc64: implement arch-specific TSC freq query).
We intended to derive pkt/sec estimation with cpu clock frequency.
As timebase register serves the timer purpose, we need to stick with it
for calculating pkt/sec, hence reverting the change.
