net/mlx4: drop MAC flows affecting all Rx queues
Configuring several Rx queues enables RSS, which causes an additional
special parent queue to be created to manage them.
MAC flows are associated with the queue supposed to receive packets; either
the parent one in case of RSS or the single orphan otherwise.
For historical reasons the current implementation supports another scenario
with multiple orphans, in which case MAC flows are configured on all of
them. This is harmless but useless since it cannot happen.
Removing this feature allows dissociating the remaining MAC flow from Rx
queues and store it inside the private structure where it belongs.

net/mlx5: replace memory barrier type
The reason for the requirement of a barrier between the txq writes
and the doorbell record writes is to avoid a case where the device
reads the doorbell record's new value before the txq writes are flushed
to memory.
The current use of rte_wmb is not necessary, and can be replaced by
rte_io_wmb which is more relaxed.
Replacing the rte_wmb is also expected to improve the throughput.

net/nfp: handle packets with length 0 as usual ones
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.

test/log: fix dynamic log levels testing
This patch fixes the dynamic log levels testing in logs_autotest.
Introduction of rte_log_set_level() in patch
c1b5fa94a46f was done
with parameter RTE_LOG_EMERG which caused all RTE_LOG() calls an
early return due to all given levels were far below EMERG.
If first two logs supposed to show up on console, the initial log
level must be low (DEBUG). It is than changed above ERR when we test
if TESTAPP2 log type can be filtered by log type log level.

cmdline: fix warning for unused return value
When DPDK is compiled on Ubuntu with extra warnings turned on, there is a
warning about the return value from write() being unchecked. Rather than
having builds disable the warning, which may mask other cases we do care
about, we can add a dummy use of the return value in the code to silence it
in this instance.
