This has three main benefits:
- tun_alloc is now generic again for any queue,
- mtu no longer needs to be handled in tap_setup_queue(),
- an actual netdevice is created as soon as the device is probed.
On top of it, code in eth_dev_tap_create() has been reworked to have a
more logical behavior; initialization can now fail if a remote is

doc: announce ABI change for Tx offload
This is an ABI change notice for DPDK 17.08 in ethdev
about changes in rte_eth_txmode structure.
Currently Tx offloads are enabled by default, and can be disabled
using ETH_TXQ_FLAGS_NO* flags. This behaviour is not consistent with
the Rx side where the Rx offloads are disabled by default and enabled
according to bit field in rte_eth_rxmode structure.
The proposal is to disable the Tx offloads by default, and provide
a way for the application to enable them in rte_eth_txmode structure.
Besides of making the Tx configuration API more consistent for
applications, PMDs will be able to provide a better out of the
box performance.
Finally, as part of the work, the ETH_TXQ_FLAGS_NO* will
be superseded as well.

doc: announce ABI change for device parameters
The PCI and virtual bus are planned to be moved to the generic
drivers/bus directory in v17.08. For this change to be possible, the EAL
must be made completely independent.
The rte_devargs structure currently holds device representation internal
to those two busses. It must be made generic before this work can be
completed.
Instead of using either a driver name for a vdev or a PCI address for a
PCI device, a devargs structure will have to be able to describe any
possible device on all busses, without introducing dependencies on
any bus-specific device representation. This will break the ABI for this
structure.
Additionally, an evolution will occur regarding the device parsing
from the command-line. A user must be able to set which bus will handle
which device, and this setting is integral to the definition of a
device.
The format has not yet been formally defined, but a proposition will
follow soon for a new command line parameter format for all devices.

This patch introduces specific functions for incrementing or
decrementing the device counter for a specific vfio group using the
vfio file descriptor as a parameter. Note the code is not optimized
as the vfio group is found sequentially going through the vfio group
