devtools: fix build test config inheritance from env

The variables DPDK_MESON_OPTIONS, PATH, PKG_CONFIG_PATH,
CPPFLAGS, CFLAGS and LDFLAGS can be customized in the config file
loaded by devtools/load-devel-config at each build.
The configuration can be adjusted per target thanks to the value set
in the DPDK_TARGET variable.

PKG_CONFIG_PATH is specific to each target, so it must be empty
before configuring each build from the file according to DPDK_TARGET.
Inheriting a default PKG_CONFIG_PATH for all targets does not make sense
and is prone to confusion.

DPDK_MESON_OPTIONS might take a global initial value from environment
to customize a build test from the shell. Example:
DPDK_MESON_OPTIONS="b_lto=true"
Some target-specific options can be added in the configuration file:
DPDK_MESON_OPTIONS="$DPDK_MESON_OPTIONS kernel_dir=$MYKERNEL"

usertools: fix pmdinfo parsing

This script inspects an ELF file (binary or shared library) and its
linked dependencies by following DT_NEEDED tags.
So far a simple librte_pmd prefix was used as a filter to only parse
DPDK drivers dependencies.
While the reason is not clear from the commitlog of the patch that
introduced this filter, it was probably added for performance reasons,
since going through all dependencies can be quite long.
Testing with a DPDK built before the driver name changes:
- running the script takes ~0.3s with the filter,
- running the script takes ~9s without the filter,

Now that we changed the driver library names, it becomes more difficult
to identify only DPDK drivers, but we can just filter on the librte_
prefix to identify DPDK libraries: the script later checks for the
PMD_INFO_STRING string in .rodata and it is enough to differentiate the
DPDK drivers from the other DPDK libraries.

Running the script with this patch takes ~0.5s.

A debug message was logged for each inspected file, it gives no useful
information and is removed.

app/flow-perf: configure rule batches

Currently, flow-perf measures the performance of
rule installation/deletion operations by breaking
down the entire number of operations into windows
of fixed size (i.e., 100000 operations per window).
Then, flow-perf measures the total time per window
and computes an average time across all windows.

This commit allows flow-perf users to configure
the number of rules per window instead of using
a fixed pre-compiled value. To do so, users must
pass --rules-batch=N, where N is the number of
rules per window (or batch).
For consistency reasons, flow_count variable is
now renamed to rules_count. This variable is the
total number of rules to be installed/deleted.

For example, if a user wants to measure how much
time it takes to install 1M rules in a certain NIC,
he/she can input:
--rules-count=1000000
This way flow-perf will break down 1M flow rules into
10 batches of 100k flow rules each (this is the default
batch size) and compute an average across the 10
measurements.
Now, if the user modifies the number of rules per
batch as follows:
--rules-count=1000000 --rules-batch=500000
then flow-perf will break down 1M flow rules into
2 batches of 500k flow rules each and compute the
average across the 2 measurements.

Finally, this commit also adds default variables
to the usage function instead of hardcoded values.

net/bnxt: fix VXLAN decap offload

This patch fixes a couple of scenarios which were overlooked
by the patch which added VXLAN rte_flow offload support.

1. When a PMD application queries for flow counters, it could ask PMD
   to reset the counters when the application is doing the counters
   accumulation. In this case, PMD should not accumulate rather reset
   the counter.

2. Some of the PMD applications may set the protocol field in the IPv4
   spec but don't set the mask. So, consider the mask in the proto
   value calculation.

4. The cached tunnel inner flow is not getting installed in the
   context of tunnel outer flow create because of the wrong
   error code check when tunnel outer flow is installed in the
   hardware.

5. When a dpdk application offloads the same tunnel inner flow on
   all the uplink ports, other than the first one the driver rejects
   the rest of them. However, the first tunnel inner flow request
   might not be of the correct physical port. This is fixed by
   caching the tunnel inner flow entry for all the ports on which
   the flow offload request has arrived on. The tunnel inner flows
   which were cached on the irrelevant ports will eventually get
   aged out as there won't be any traffic on these ports.

net/hns3: fix configurations of port-level scheduling rate

Scheduling rate of port-level in hns3 PF driver configured to

bandwidth capability of the port. The rate in firmware is
generally configured with the maximum value for network engine
supporting multiple rates, such as 10G and 25G. It may cause
the following issues:
1) When a 10G optical module is used on the network engine, scheduling
   rate of this port will also be configured to hardware with 25G.
   However, the MAC rate of this port is 10G. In this case, it is
   unreasonable that the port scheduling rate is different from the MAC
   rate.
2) If default speed in firmware is not the maximum value, the 25G port
   may not reach the capability of the port.

Therefore, we fix configurations of port-level scheduling rate
according to updating of MAC link speed.
