The dpdk-devbind.py script does not find/display the ifname for virtio
interfaces since the "net" directory is not directly under the device
directory but rather under a subdirectory.
eg.
> dpdk-devbind.py --status
0000:00:03.0 'Virtio network device' if= drv=virtio-pci unused=
This change searches for the first "net" directory under the device
directory hierarchy.
eg.
0000:00:03.0 'Virtio network device' if=ens3 drv=virtio-pci unused=

Using dpdk-pmdinfo with the '-r' flag does not produce a json output as
documented. Instead, the python representation of the json object is
shown, which is nearly the same, but cannot be properly parsed by a json
parser.
python repr (before):
{u'pci_ids': [[5549, 1968, 65535, 65535]], u'name': u'vmxnet3'}
json (after):
{"pci_ids": [[5549, 1968, 65535, 65535]], "name": "vmxnet3"}

The following tools may be installed system-wide.
It may be cleaner and more convenient to find them with the same
dpdk- prefix (especially for autocompletion).
Moreover, the script dpdk_nic_bind.py deserves a new name because it is
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.

There were a couple of issues which prevented pmdinfo.py from running on
FreeBSD, both of which are fixed by this patch.
* The path to python is not /usr/bin/python as on Linux, so use
/usr/bin/env to find it on both OS's.
* The path to the pci ids DB is in a different location on FreeBSD,
so use the platform python library to look in different default
locations depending on the underlying OS. [There are two possible
locations to look on FreeBSD, as defined by pciconf manpage, so
check in both in order of better to worse]

This tool searches for the primer sting PMD_DRIVER_INFO= in any ELF binary,
and, if found parses the remainder of the string as a json encoded string,
outputting the results in either a human readable or raw, script parseable
format
Note that, in the case of dynamically linked applications, pmdinfo.py will
scan for implicitly linked PMDs by searching the specified binaries
.dynamic section for DT_NEEDED entries that contain the substring
librte_pmd. The DT_RUNPATH, LD_LIBRARY_PATH, /usr/lib and /lib are
searched for these libraries, in that order
If a file is specified with no path, it is assumed to be a PMD DSO, and the
LD_LIBRARY_PATH, /usr/lib[64]/ and /lib[64] is searched for it
Currently the tool can output data in 3 formats:
a) raw, suitable for scripting, where the raw JSON strings are dumped out
b) table format (default) where hex pci ids are dumped in a table format
c) pretty, where a user supplied pci.ids file is used to print out vendor
and device strings

Currently dpdk_nic_bind.py detects Linux kernel modules via reading
/proc/modules. Built-in ones aren't listed there and therefore they are
not being found by the script.
Add support for checking built-in modules with parsing the sysfs files.

The uninstall procedure cannot be applied properly (without removing

As it is a packaging issue, it is removed from the build system capabilities.

This patch fixes several minor issues in setup.sh:
- show_nics() would not display the current Ethernet settings if
the user only loads the vfio-pci module, b/c it only checks for
presence of igb_uio. Fix this by adding a check for vfio-pci.
- unbind_nics(): Fix option naming and string inside function.
- Exchange a forgotten "igb_uio" with "vfio-pci" in a comment.

The dpdk_nic_bind script will not allow ports to be bound or unbound if none of the
kernel modules supported by DPDK is loaded. This patch relaxes this restriction by
checking if a DPDK module is actually requested. The example below illustrates this
problem:
In virtio test, on the guest
1. Bind virtio port to igb_uio driver;
2. Remove igb_uio module;
3. Bind virtio port to virtio-pci driver, it fails and reports:
"Error - no supported modules are loaded"
The script should check the to-be-bound driver flag, if it is dpdk driver(igb_uio, vfio etc),
and the corresponding module is not loaded, then exit, otherwise, just report a warning,
and continue to bind the non-dpdk driver(like virtio-pci) to dev.

When binding devices to a generic driver (i.e. one that doesn't have a
PCI ID table, some devices that are not bound to any other driver could
be bound even if no one has asked them to. hence, we check the list of
drivers again, and see if some of the previously-unbound devices were
erroneously bound. if such devices are found, they are unbound back.

Removing PCI ID list to make igb_uio more similar to a generic driver
like vfio-pci or pci_uio_generic. This is done to make it easier for
the binding script to support multiple drivers.
Note that since igb_uio no longer has a PCI ID list, it can now be
bound to any device, not just those explicitly supported by DPDK. In
other words, it now behaves similar to PCI stub, VFIO and other generic
PCI drivers.
Therefore to bind a new device to igb_uio, the user will now have to
first write its PCI ID to "new_id" file inside the igb_uio driver
directory, and only then write the PCI ID to "bind". This is reflected
in changes to PCI binding script as well.
There's a weird behaviour of sysfs when a new device ID is added to
new_id. Subsequent writing to "bind" will result in IOError on
closing the file. This error is harmless but it triggers the
exception anyway, so in order to work around that, we check if the
device was actually bound to the driver before raising an error.
