Vector PMD returns buffers to the application without setting the pointers
in the Rx queue to null nor allocating them. When the PMD cleanup the ring
it needs to take a special care to those pointers to not free the mbufs
before the application have used them nor if the application have already
freed them.

To use the vector, it needs to add to the PMD Rx mbuf ring four extra mbuf
to avoid memory corruption. This additional mbuf are added on dev_start()
whereas all other mbuf are allocated on queue setup.
This patch brings this allocation back to the same place as other mbuf
allocation.

We need to support how firmware metadata was handled until now and also
the new API, since NFP NFD 3.0 firmware versions. The new metadata API
adds flexibility for working with different metadata types and, mainly,
to allow adding metadata from different firmware components independently.
Although this patch just supports one type handled by the PMD, future uses
regarding firmware apps will extend this support.

A DPDK app could, whatever the reason, send packets with size 0.
The PMD is not sending those packets, which does make sense,
but the problem is the mbuf is not released either. That leads
to mbufs not being available, because the app trusts the
PMD will do it.
Although this is a problem related to app wrong behavior, we
should harden the PMD in this regard. Not sending a packet with
size 0 could be problematic, needing special handling inside the
PMD xmit function. It could be a burst of those packets, which can
be easily handled, but it could also be a single packet in a burst,
what is harder to handle.
It would be simpler to just send that kind of packets, which will
likely be dropped by the hw at some point. The main problem is how
the fw/hw handles the DMA, because a dma read to a hypothetical 0x0
address could trigger an IOMMU error. It turns out, it is safe to
send a descriptor with packet size 0 to the hardware: the DMA never
happens, from the PCIe point of view.

Flow control watermark is not read out correctly,
that may cause an application who not intend to change
watermark but does change it with a rte_eth_dev_flow_ctrl_set
call right after rte_eth_dev_flow_ctrl_get.
The idea fix is, during init, the watermark is set with default value,
so it is not necessary to read out from hw register during flow_ctl_get,
But due to I40E_GLRPB_GHW limitation, it is shared by different ports on
the same device, it is possible the value is changed on another port,
but local variable not sync, so we have to read out register every
flow_ctl_get.

The patch simplifies DPDK applications analysis for developers which use
Intel® VTune Amplifier.
The empty cycles are such iterations that yielded no RX packets. As far as
DPDK is running in poll mode, wasting cycles is equal to wasting CPU time.
Tracing such iterations can identify that device is underutilized. Tracing
empty cycles becomes even more critical if a system uses a lot of Ethernet
ports.
The patch gives possibility to analyze empty cycles without changing
application code. All needs to be done is just to reconfigure and rebuild
the DPDK itself with CONFIG_RTE_ETHDEV_PROFILE_ITT_WASTED_RX_ITERATIONS
enbled. The important thing here is that this does not affect DPDK code.
The profiling code is not being compiled if user does not specify config
flag.

In DPDK 17.08, the script has been fixed to ignore tags from
non current branch.
It was using the option --merged which was introduced in git 2.7.0.
As git 2.7.0 is not so old, a fallback is provided for some years.
The fallback is replacing the tag --merged option by a branch filter.
If the tag is found in the branch, the branch name is replaced
by the tag.
This script could be improved to allow using another reference branch,
instead of hard coding HEAD branch (the current one).
