1d64e46eb8 ring: allow to initialize without memzone
Allow to initialize a ring in an already allocated memory. The rte_ring_create()
function that allocates a ring in a rte_memzone is still available and now uses
the new rte_ring_init() function in order to factorize the code.

5d8751b83b pci: remove deprecated RTE_EAL_UNBIND_PORTS option
RTE_EAL_UNBIND_PORTS was deprecated in DPDK 1.4.0 and removed in 1.6.0, but the
code was not removed.

The bind/unbind operations should not be handled by the eal.
These operations should be either done outside of dpdk or inside the PMDs
themselves as these are their problems.

d8deab8a88 pci: pci_switch_module cleanup
The pci_switch_module() function should only do what its name tells: unbind pci
devices and rebind them on the specified kernel driver.
Hence, it can not call pci_uio_map_resource().

Call to pci_uio_map_resource() should be moved to rte_eal_pci_probe_one_driver()
so that we can factorize code.

There is no need for a 'magic' field in struct rte_config, as this part of the
structure is local to each process. All threads of a process are synchronised
because of the run_once atomic.
So remove this field, as it is only adding confusion when reading code that

221fb04df9 mk: fix build ignoring other installed versions
If some DPDK libraries are installed on the system, the linker was trying
to use them before searching in -L path.
The obscure reason is that we were prefixing -L with -Wl, to pass it
directly to the linker.
But -L is also a gcc option. And allowing gcc to process this option fixes

9ad0e24942 eal: fix vdev allocation on non-0 numa socket
vdev ethdev can not be allocated on a numa socket that is not socket 0.
The reason comes from rte_eth_dev_allocate() which uses rte_socket_id() to
identify the socket on which vdev driver data should be allocated.
However, at this initialization step, rte_socket_id() always returns 0.

Looking at rte_socket_id(), it needs rte_lcore_id() which uses the per-core
global _lcore_id variable. This variable is initialised by
eal_thread_init_master.

So eal_thread_init_master should be called before rte_eal_vdev_init().

("PCI: Add accessors for PCI Express Capability", v3.7-rc1)).

It results in the same compilation error as redhat 6.x.
However, there is no clear way to determine we are building on a debian kernel.
So, rather than determine if we are building on a distribution kernel, look at
PCI_EXP_LNKSTA2 that appeared in this upstream commit.

894fd42e7f eal: do not try to load library from current directory
When loading a library "libfoo.so" (depending on "libbar.so", located in an
entirely different folder), with a LD_LIBRARY_PATH=/path/to/libfoo.so", it
returns an error:

 EAL: ./libfoo.so: cannot open shared object file: No such file or directory

If the first dlopen() fails (here, because it can't find all dependencies),
the code requires for a second dlopen() that looks for "./libfoo.so". It
turns on pathname matching, which does not use LD_LIBRARY_PATH. As a result,
it fails because it cannot find "./libfoo.so".

The error message matches the error of the second dlopen(), not the first's.

Do not try to look for a different library ("./"-prefixed) than the one
provided in argument. Let the dynamic library management handle it, just
provide an appropriate LD_LIBRARY_PATH.

So this check will return an error with a more explicit message in

6383201503 mk: pass CROSS_COMPILE when compiling kernel modules
Pass CROSS_COMPILE to the kernel build system when compiling kernel
modules. Although we export CC etc. the top level kernel Makefile will
override the environment. As a result it will end up using wrong tools
if cross-compilation is desired but CROSS_COMPILE is not set.

396b69e56a vdev: allow external registration of virtual device drivers
The registration of an external vdev driver (a .so library) is done in a
function that has the ((constructor)) attribute. This function is called
when dlopen(driver.so) is invoked.

As a result, we need to do the dlopen() before calling
rte_eal_vdev_init() that calls the initialization functions of all
registered drivers.

4c39baf297 vdev: new registration API
Instead of having a list of virtual device drivers in EAL code, add an
API to register drivers. Thanks to this new registration method, we can
remove the references to pmd_ring, pmd_pcap and pmd_xenvirt in EAL code.
This also enables the ability to register a virtual device driver as
a shared library.

The registration is done in an init function flaged with
__attribute__((constructor)). The new convention is to name this
function rte_pmd_xyz_init(). The per-device init function is renamed
rte_pmd_xyz_devinit().

By the way the internal PMDs are now also .so/standalone ready. Let's do
it later on. It will be required to ease maintenance.

9fa5e2b026 vdev: rename nonpci_devs as vdev
The name "nonpci_devs" for virtual devices is ambiguous as a physical
device can also be non-PCI (ex: usb, sata, ...). A better name for this
file is "vdev" as it only deals with virtual devices.

This patch doesn't introduce any change except renaming.
