On the code after the below commits, the criteria to select the IPV4 or
IPV6 hash functions was the existence of some ETH_RSS_IPV4 RSS types on
the flow rule.
The check is wrong. For example ETH_RSS_NONFRAG_IPV4_TCP will not select
the IPV4 hash which will cause the packet to be spread in a bad way.
Fix it by adding the corresponding types needed for each hash selection.

On ConnectX-4 Lx the Multi Packet Send (MPW) feature is considered
un-secure, as on some cases were the application provides incorrect mbufs
on the Tx burst the host or NIC can get stuck.
Hence, disabling the feature by default for this specific NIC.
Users can still enable this feature and enjoy the performance gain
(mostly for low number of cores) by using the txq_mpw_en devarg.
This patch will impact the out of the box performance of some application
using ConnectX-4 Lx for the sack of security and robustness.
Since we need different defaults based on the underlying device the mpw
field in the configuration struct was extended to contain also the
MLX5_ARG_UNSET option.

The event buffer was changed to be a fixed size value,
had a couple of issues. The big one is that rte_free was still
being called for a pointer that was not setup with rte_malloc().
The event buffer was also too small to handle heavy receive
traffic; and running the event buffer out would crash
the application.
Fix by going back to a dynamically resized event buffer.
And grow it by 25% to avoid lots of realloc's.

The patch changes rx_burst profiling approach:

2. empty hook callback for profiling is added
This way all VTune-specific logic moves to the VTune side.
Hook is enabled only when CONFIG_RTE_ETHDEV_PROFILE_WITH_VTUNE option
is turned on. VTune uses this hook to attach to the polling cycle. It
is not possible to attach to the rx_burst directly, as it is inline.

If user specifies priority=0 for some of ACL rules
that can cause rte_acl_classify to return wrong results.
The reason is that priority zero is used internally for no-match nodes.
See more details at: https://bugs.dpdk.org/show_bug.cgi?id=79.
The simplest way to overcome the issue is just not allow zero
to be a valid priority for the rule.

It was reported recently that some patches that add symbols to an
existing EXPERIMENTAL section of a version map file generate errors
because the check-symbol-change script was identifying the section as
"@@" rather than EXPERIMENTAL. This was fairly clearly due to the fact
that the rule identifying the version section expected the whole section
to be added, rather than having it already exist, with only new symbols
being added to the existing section. This led the match rule to misread
the format of that line and pull the wrong word out of it.
The fix is to relax the rule slightly. Rather than assume that the
section must exist on a line that was added, allow the section name to
be set by any line that ends in a '{', which should be correct, given
our coding practices. The section name is then extracted as the next to
the last word on the line ( $(NF-1) ).

The size of Rx queue is determined by dividing the number of descriptors by
the number of strides. As device can't support single slot queue, if the
number of descriptors is same as the number of strides, MPRQ shouldn't be
enabled. Otherwise, this will cause HW fault. For example, if rxd is set to
512 with testpmd on ConnectX-4 Lx, PMD can't receive more than 512 packets
because the minimum number of strides for ConnectX-4 Lx is 512. Users have
to configure larger number of descriptors in this case.
