Use of rte_smb_wmb() instead of rte_smb_rmb() in sc dequeue function
creates the additional overhead of waiting for all the STOREs
to be completed to local buffer from ring buffer memory.
The sc dequeue function demands only LOAD-STORE barrier where LOADs
from ring buffer memory needs to be completed before tail pointer update.
Changing to rte_smb_rmb() to enable the required LOAD-STORE barrier.

There is a dependency on librt with old glibc.
The -lrt option was added everywhere it is needed but was also
added in some applications makefiles as the first link option.
The problem is this option is really useful only if added after
the objects or libraries using it (except if using --whole-archive).
And the -lrt options put after were removed to avoid duplicates.
It was resulting in errors linking test application:
eal_timer.c:(.text+0x128): undefined reference to `clock_gettime'
eal_timer.c:(.text+0x166): undefined reference to `clock_gettime'
eal_alarm.c:(.text+0xda): undefined reference to `clock_gettime'

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

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

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.

We find significant perfermance drop introduced by below commit,
when vhost example is started with --mergeable 0 and inside vm,
kernel virtio-net driver is used to do ip based forwarding.
The commit, 859b480d5afd ("vhost: add guest offload setting"), adds
support for VIRTIO_NET_F_GUEST_TSO4 and VIRTIO_NET_F_GUEST_TSO6,
in vhost lib. But inside vhost example, the way to disable tso only
excludes the direction from virtio to vhost, but not the opposite
direction. When mergeable is disabled, it triggers big_packets path
of virtio-net driver to prepare to receive possible big packets with
size of 64K. Because mergeable is off, for each entry of avail ring,
virtio driver uses 19 desc chained together, with one desc pointing
to header, other 18 desc pointing to 4K-sized pages. But QEMU only
creates 256 desc entries for each vq, which results in that only 13
packets can be received. VM kernel can quickly handle those packets
and go to sleep (HLT).
As QEMU has no option to set the desc entries of a vq, so here,
we disable VIRTIO_NET_F_GUEST_TSO4 and VIRTIO_NET_F_GUEST_TSO6
with VIRTIO_NET_F_HOST_TSO4 and VIRTIO_NET_F_HOST_TSO6 when we
disable tso of vhost example, to avoid VM kernel virtio driver
go into big_packets path.
