The right name of ethdev should be dpdk_netdev. However:
1/ We are using rte_ prefix in the code and library names.
2/ The API uses rte_ethdev
That's why 16.11 will just have the rte_ prefix prepended to
the library filename as every other libraries.

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

Flow Bifurcation is a mechanism which uses features of advanced
Ethernet devices to split traffic between queues. It provides
the capability to let the kernel driver and DPDK driver co-exist
and take advantage of both.
It is achieved by using SR-IOV and the NIC's advanced filtering. This
patch describes Flow Bifurcation and adds the user guide for ixgbe
and i40e NICs.

The vhost feature negotiation only happens at virtio reset stage, say
when a virtio-net device is firstly initiated, or when DPDK virtio PMD
initiates. That means, if vhost APP restarts after the negotiation and
reconnects, the feature negotiation process will not be triggered again,
meaning the info is lost. To make reconnect work, QEMU simply saves
the negotiated features before the restart and restores it afterwards.
Therefore, the vhost supported features must be exactly the same before
and after the restart. For example, if TSO is disabled and then enabled,
nothing will work and undefined issues might happen.

CONFIG_IO_STRICT_DEVMEM is introduced in Linux v4.5 and not enabled

Linux commit: 90a545e restrict /dev/mem to idle io memory ranges
As a workaround igb_uio can stop reserving PCI memory resources, from
kernel point of view iomem region looks like idle and mmap works
again. This matches uio_pci_generic usage.
With this update device iomem range is not protected against any
other kernel drivers or userspace access. But this shouldn't
be a problem for dpdk usage module since purpose of the igb_uio
module is to provide userspace access.

The mempool_count and mempool_free_count behaved contrary to what their
names suggested. The free_count function actually returned the number of
elements that were allocated from the pool, not the number unallocated as
the name implied.
Fix this by introducing two new functions to replace the old ones,
* rte_mempool_avail_count to replace rte_mempool_count
* rte_mempool_in_use_count to replace rte_mempool_free_count
In this patch, the new functions are added, and the old ones are marked
as deprecated. All apps and examples that use the old functions are
updated to use the new functions.

The standard Virtual Ethernet Bridge(VEB) definition in 1Qbg is a bridge
which has an uplink port to the outside world (maybe another bridge), but
a "floating" VEB is a special VEB without an uplink port to the outside.
Instead, traffic can be sent from one VF to another using the floating
VEB - even when the physical link on the NIC port is down.
This patch adds floating VEB options in the devargs for i40e driver.
Using these parameters, applications can decide whether to use legacy
VEB/VEPA or a floating VEB.
To enable this feature, the user should pass a devargs parameter to the
EAL, for example "-w 84:00.0,enable_floating_veb=1", to control whether
the PMD will to use the floating VEB feature or not.
Once the floating VEB feature is enabled, all the VFs created by
this PF device are connected to the floating VEB.
NOTE: The floating VEB functionality requires a NIC firmware version
of 5.0 or greater.
