ICC build time
Before this patch (bnx2x PMD enabled [1])
real 8m16.622s
After this patch (bnx2x enabled)
real 0m35.140s
[1]
bnx2x cause the build take a lot, otherwise build times are more sane
numbers.
ICC has a default inline limit and when this limit is hit it generates
a warning, and in DPDK this breaks the build.
Previous solution was to remove the inline limit, which does more
aggressive inlining and build may take too much time.
This patch keeps the default inline limits, but prevents the warning ICC
generates.

Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC without -j).
- for instance, it is possible to express a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.

Downstreams might want to provide different DPDK releases at the same
time to support multiple consumers of DPDK linked against older and newer
sonames.
Also due to the interdependencies that DPDK libraries can have applications
might end up with an executable space in which multiple versions of a
library are mapped by ld.so.
Think of LibA that got an ABI bump and LibB that did not get an ABI bump
but is depending on LibA.
Application
\-> LibA.old
\-> LibB.new -> LibA.new
That is a conflict which can be avoided by setting CONFIG_RTE_MAJOR_ABI.
If set CONFIG_RTE_MAJOR_ABI overwrites any LIBABIVER value.
An example might be ``CONFIG_RTE_MAJOR_ABI=16.11`` which will make all
libraries librte<?>.so.16.11 instead of librte<?>.so.<LIBABIVER>.
We need to cut arbitrary long stings after the .so now and this would work
for any ABI version in LIBABIVER:
$(Q)ln -s -f $< $(patsubst %.$(LIBABIVER),%,$@)
But using the following instead additionally allows to simplify the Make
File for the CONFIG_RTE_NEXT_ABI case.
$(Q)ln -s -f $< $(shell echo $@ | sed 's/\.so.*/.so/')

Since "make test" and "make test-build" does dependency resolving, they
check for all dependent components (lib and drivers) which takes a few
seconds.
This is a good feature during development, but if the target is only
running unit test, that step is unnecessary, it is possible to compile
once and run unit test multiple times, without checking any code update.
For this purpose, a new make rule "make test-basic" added. Which only
runs the unit test, expects that unit test already compiled.

Some PMDs provide device specific APIs. Bond and xenvirt are existing
samples for this.
And since these are PMD libraries, there are two options on how to link
them for shared library build:
1- They can be linked to all applications by default, using common
rte.app.mk file.
2- They can be explicitly linked to applications that use device
specific API.
Currently option one is in use, this patch switches to the option two.
Moves library linking to the Makefile of application Makefile that uses
device specific API.
This prevent these PMD libraries to be a dependency to applications
that don't use these device specific APIs.

Wrapped libraries are mainly PMD libraries, this is required because PMD

Also some set of libraries, depends to the PMD libraries needs this,
because of same reason.
All the libraries used by a plugin (any driver) must be in

Elastic Flow Distributor (EFD) is a distributor library that uses
perfect hashing to determine a target/value for a given incoming flow key.
It has the following advantages:
- First, because it uses perfect hashing, it does not store
the key itself and hence lookup performance is not dependent
on the key size.
- Second, the target/value can be any arbitrary value hence
the system designer and/or operator can better optimize service rates
and inter-cluster network traffic locating.
- Third, since the storage requirement is much smaller than a hash-based
flow table (i.e. better fit for CPU cache), EFD can scale to
millions of flow keys.
Finally, with current optimized library implementation performance
is fully scalable with number of CPU cores.
