08c028d08c net/mlx: fix rdma-core glue path with EAL plugins
Glue object files are looked up in RTE_EAL_PMD_PATH by default when set and
should be installed in this directory.

During startup, EAL attempts to load them automatically like other plug-ins
found there. While normally harmless, dlopen() fails when rdma-core is not
installed, EAL interprets this as a fatal error and terminates the
application.

This patch requests glue objects to be installed in a different directory
to prevent their automatic loading by EAL since they are PMD helpers, not
actual DPDK plug-ins.

0f872d3129 net/enic: support Rx queue interrupts
Enable rx queue interrupts if the app requests them, and vNIC has
enough interrupt resources. Use interrupt vector 0 for link status and
errors. Use vector 1 for rx queue 0, vector 2 for rx queue 1, and so
on. So, with n rx queues, vNIC needs to have at n + 1 interrupts.

For VIC, enabling and disabling rx queue interrupts are simply
mask/unmask operations. VIC's credit based interrupt moderation is not
used, as the app wants to explicitly control when to enable/disable
interrupts.

This version requires MSI-X (vfio-pci). Sharing one interrupt for link
status and rx queues is possible, but is rather complex and has no
user demands.

422ba91716 net/enic: heed the requested max Rx packet size
Currently, enic completely ignores the requested max Rx packet size
(rxmode.max_rx_pkt_len). The desired behavior is that the NIC hardware
drops packets larger than the requested size, even though they are
still smaller than MTU.

Cisco VIC does not have such a feature. But, we can accomplish a
similar (not same) effect by reducing the size of posted receive
buffers. Packets larger than the posted size get truncated, and the
receive handler drops them. This is also how the kernel enic driver
enforces the Rx side MTU.

This workaround works only when scatter mode is *not* used. When
scatter is used, there is currently no way to support
rxmode.max_rx_pkt_len, as the NIC always receives packets up to MTU.

For posterity, add a copious amount of comments regarding the
hardware's drop/receive behavior with respect to max/current MTU.

c2fec27b5c net/enic: allow to change RSS settings
Currently, when more than 1 receive queues are configured, the driver
always enables RSS with the driver's own default hash type, key, and
RETA. The user is unable to change any of the RSS settings. Address
this by implementing the ethdev RSS API as follows.

Correctly report the RETA size, key size, and supported hash types
through rte_eth_dev_info.

During dev_configure(), initialize RSS according to the device's
mq_mode and rss_conf. Start with the default RETA, and use the default
key unless a custom key is provided.

Add the RETA and rss_conf query/set handlers to let the user change
RSS settings after the initial configuration. The hardware is able to
change hash type, key, and RETA individually. So, the handlers change
only the affected settings.

Refactor/rename several functions in order to make their intentions
clear. For example, remove all traces of RSS from
enicpmd_vlan_offload_set() as it is confusing.

096dba799b net/sfc: avoid creation of ineffective flow rules
Despite being versatile, the hardware support for filtering has a number
of special properties which must be taken into account. Namely, there is
a known set of valid filters which don't take any effect despite being
accepted by the hardware.

The combinations of match flags and field values which can describe the
exceptional filters are as follows:
- ETHER_TYPE or ETHER_TYPE | LOC_MAC with IPv4 or IPv6 EtherType
- ETHER_TYPE | IP_PROTO or ETHER_TYPE | IP_PROTO | LOC_MAC with UDP or
TCP IP protocol value
- The same combinations with OUTER_VID and/or INNER_VID

These exceptional filters can be expressed in terms of RTE flow rules.
If the user creates such a flow rule, no traffic will hit the underlying
filter, and no errors will be reported.

This patch adds a means to prevent such ineffective flow rules from
being created.

2606bdd249 net/cxgbe: rework and use 32-bit port capability
The new code uses the new 32-bit Port Capabilities exclusively and
only translates to/from the old 16-bit Port Capabilities at the last
point possible when talking to older Firmware.

For the old versus new Firmware issue, we use the new FW_PARAMS_CMD[PFVF,
CAPS32] command to tell the Firmware that we want Asynchronous Port Status
updates to use the new 32-bit version of the Port Information message.  If
we get an error, we know we're dealing with older Firmware, and if not,
we'll start getting th new 32-bit Port Capability message formats.

Also, refactor t4_handle_fw_rpl() to handle new 32-bit Port Capability
replies from firmware in t4_handle_get_port_info().

c06ddf9698 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%.

59b91bec12 net/mlx5: spawn rdma-core dependency plug-in
When mlx5 is not compiled directly as an independent shared object (e.g.
CONFIG_RTE_BUILD_SHARED_LIB not enabled for performance reasons), DPDK
applications inherit its dependencies on libibverbs and libmlx5 through
rte.app.mk.

This is an issue both when DPDK is delivered as a binary package (Linux
distributions) and for end users because rdma-core then propagates as a
mandatory dependency for everything.

Application writers relying on binary DPDK packages are not necessarily
aware of this fact and may end up delivering packages with broken
dependencies.

This patch therefore introduces an intermediate internal plug-in
hard-linked with rdma-core (to preserve symbol versioning) loaded by the
PMD through dlopen(), so that a missing rdma-core does not cause unresolved
symbols, allowing applications to start normally.

8b9bd0efe0 app/testpmd: disable Rx VLAN offloads by default
Removed the hardcoded preconfigured Rx VLAN offload configuration
from testpmd and changed the Rx offload command line parameters from
disable to enable.

It has been decided by the Technical Board that testers who wish to
use these offloads will now have to explicitly write them in the
command-line when running testpmd.
The agreement is to keep two exceptions enabled by default in 18.02:
Rx CRC strip and Tx fast free.

Motivation:
Some PMDs such at the mlx4 may not implement all the offloads.
After the offload API rework assuming no offload is enabled by default,
  commit ce17eddefc ("ethdev: introduce Rx queue offloads API")
  commit cba7f53b71 ("ethdev: introduce Tx queue offloads API") trying
to enable a not supported offload is clearly an error which will cause
configuration failing.

Considering that testpmd is an application to test the PMD, it should
not fail on a configuration which was not explicitly requested.
The behavior of this test application is then turned to an opt-in
model.

5b7ba31148 ethdev: add port ownership
The ownership of a port is implicit in DPDK.
Making it explicit is better from the next reasons:
1. It will define well who is in charge of the port usage synchronization.
2. A library could work on top of a port.
3. A port can work on top of another port.

Also in the fail-safe case, an issue has been met in testpmd.
We need to check that the application is not trying to use a port which
is already managed by fail-safe.

A port owner is built from owner id(number) and owner name(string) while
the owner id must be unique to distinguish between two identical entity
instances and the owner name can be any name.
The name helps to logically recognize the owner by different DPDK
entities and allows easy debug.
Each DPDK entity can allocate an owner unique identifier and can use it
and its preferred name to owns valid ethdev ports.
Each DPDK entity can get any port owner status to decide if it can
manage the port or not.

The mechanism is synchronized for both the primary process threads and
the secondary processes threads to allow secondary process entity to be
a port owner.

Add a synchronized ownership mechanism to DPDK Ethernet devices to
avoid multiple management of a device by different DPDK entities.

The current ethdev internal port management is not affected by this
feature.

b114af1603 build: remove architecture flag as default C flag
Any flags added to the project args are automatically added to all builds,
both native and cross-compiled. This is not what we want for the -march
flag as a valid -march for the cross-compile is not valid for pmdinfogen
which is a native-build tool.

Instead we store the march flag as a variable, and add it to the default
cflags for all libs, drivers, examples, etc. This will allow pmdinfogen to
compile successfully in a cross-compilation environment.
