7d299777ec eal: remove PCI/vdev unused code
- Remove checks for VDEV from rte_eal_vdev_(init/uninint) as all devices
  are inherently virtual here.
- PDEVs perform PCI specific inits - rte_eal_dev_init() need not call
  rte_driver->init();

a160404539 eal: extract vdev infra
Move all PMD_VDEV-specific code into a separate module and header
file to not polute the generic code anymore. There is now a list
of virtual devices available.

The rte_vdev_driver integrates the original rte_driver inside
(C inheritance). The rte_driver will be however change in the
future to serve as a common base for all other types of drivers.

The existing PMDs (PMD_VDEV) are to be modified later (there is
no change for them at the moment).

e8c528cb92 eal: add hotplug operations for PCI and vdev
Hotplug invocations, which deals with devices, should come from the layer
that already handles them, i.e. EAL.

For both attach and detach operations, 'name' is used to select the bus
that will handle the request.

affe1cdc00 pci: introduce helpers for device name parsing/update
- Move rte_eth_dev_create_unique_device_name() from ether/rte_ethdev.c to
  common/include/rte_pci.h as rte_eal_pci_device_name(). Being a common
  method, can be used across crypto/net PCI PMDs.
- Remove crypto specific routine and fallback to common name function.
- Introduce a eal private Update function for PCI device naming.

af424af840 pci: replace devinit/devuninit with probe/remove
Probe and Remove are more appropriate names for PCI init and uninint
operations. This is a cosmetic change.

Only MLX* uses the PCI direct registration, bypassing PMD_* macro.
The callbacks for this too have been updated.

VDEV are left out. For them, init/uninit are more appropriate.

c00ae961ff mem: fix crash on hugepage mapping error
In ASLR-enabled system, it is possible that selected
virtual space is occupied by program segments. Therefore,
error path should not blindly unmap all memmory segments
but only those already mapped.

Steps that lead to crash:
1. memeseg 0 in secondary process overlaps with libc.so
2. mmap of /dev/zero fails for virtual space of memseg 0
3. munmap of memseg 0 leads to unmapping libc.so itself
4. app gets SIGSEGV after returning from syscall to libc

c711ccb309 ivshmem: remove library and its EAL integration
Following discussions on the mailing list [1] and since nobody stood up to
implement the necessary cleanups, here is the ivshmem integration removal.

There is not much to say about this patch, a lot of code is being removed.
The default configuration file for packet_ordering example is replaced with
the "native" x86 file.
The only tricky part is in eal_memory with the memseg index stuff.

More cleanups can be done after this but will come in subsequent patchsets.

82f9318055 contigmem: zero all pages during mmap
On Linux, all huge pages are zeroed by the kernel before
first access by the DPDK application.  But on FreeBSD,
the contigmem driver would only zero the contiguous
memory regions during initial driver load.

DPDK commit b78c91751 eliminated the explicit memset()
operation for rte_zmalloc(), which was OK on Linux
because the kernel zeroes the pages during app start,
but this broke FreeBSD when restarting app.
So this patch explicitly zeroes the pages before they are mmap'd,
to ensure equivalent behavior to Linux.

not restricted to NICs and can be used for e.g. crypto.

These files are renamed:
pmdinfogen       -> dpdk-pmdinfogen
pmdinfo.py       -> dpdk-pmdinfo.py
dpdk_pdump       -> dpdk-pdump
dpdk_proc_info   -> dpdk-procinfo
dpdk_nic_bind.py -> dpdk-devbind.py
setup.sh         -> dpdk-setup.sh

The tools pmdinfogen, pmdinfo.py and dpdk_pdump are new in 16.07.

The scripts dpdk_nic_bind.py and setup.sh may have been used with
previous releases by end users. That's why a symbolic link still
provide the old name in the installed tools directory.
