net/e1000: fix buffer overrun while i219 processing DMA

Intel® 100/200 Series Chipset platforms reduced the round-trip
latency for the LAN Controller DMA accesses, causing in some high
performance cases a buffer overrun while the I219 LAN Connected
Device is processing the DMA transactions. I219LM and I219V devices
can fall into unrecovered Tx hang under very stressfully UDP traffic
and multiple reconnection of Ethernet cable. This Tx hang of the LAN
Controller is only recovered if the system is rebooted. Slightly slow
down DMA access by reducing the number of outstanding requests.
This workaround could have an impact on TCP traffic performance
on the platform. Disabling TSO eliminates performance loss for TCP
traffic without a noticeable impact on CPU performance.

Please, refer to I218/I219 specification update:

app/testpmd: support raw encap/decap actions

This patch intend to support

Two new commands - set raw_encap, set raw_decap are introduced just

These two commands have corresponding global buffers

The commands use the rte_flow pattern syntax to help user build the

A common way to use it:

- encap matched egress packet with VxLAN tunnel:

testpmd> flow create 0 egress pattern eth / ipv4 / end actions
 raw_encap / end

- decap l2 header and encap GRE tunnel on matched egress packet:

net/mlx5: accelerate DV flow counter query

All the DV counters are cashed in the PMD memory and are contained in
pools which are contained in containers according to the counters
allocation type - batch or single.

Currently, the flow counter query is done synchronously in pool
resolution means that on the user request a FW command is triggered to
read all the counters in the pool.

A new feature of devX to asynchronously read batch of flow counters
allows to accelerate the user query operation.

Using the DPDK host thread, the PMD periodically triggers asynchronous
query in pool resolution for all the counter pools and an interrupt is
triggered by the FW when the values are updated.
In the interrupt handler the pool counter values raw data is replaced
using a double buffer algorithm (very fast).
In the user query, the PMD just returns the last query values from the
PMD cache - no system-calls and FW commands are triggered from the user
control thread on query operation!

More synchronization is added with the host thread:
        Container resize uses double buffer algorithm.
        Pools growing in container uses atomic operation.
        Pool query buffer replace uses a spinlock.

net/mlx5: accelerate DV flow counter transactions

The DevX interface exposes a new feature to the PMD that can allocate a
batch of counters by one FW command. It can improve the flow
transaction rate (with count action).

Add a new counter pools mechanism to manage HW counters in the PMD.
So, for each flow with counter creation the PMD will try to find a free
counter in the PMD pools container and only if there is no a free
counter, it will allocate a new DevX batch counters.

Currently we cannot support batch counter for a group 0 flow, so
create a 2 container types, one which allocates counters one by
one and one which allocates X counters by the batch feature.

The allocated counters objects are never released back to the HW
assuming the flows maximum number will be close to the actual value of
the flows number.
Later, it can be updated, and dynamic release mechanism can be added.

The counters are contained in pools, each pool with 512 counters.
The pools are contained in counter containers according to the
allocation resolution type - single or batch.
The cache memory of the counters statistics is saved as raw data per
pool.
All the raw data memory is allocated for all the container in one
memory allocation and is managed by counter_stats_mem_mng structure
which registers all the raw memory to the HW.
Each pool points to one raw data structure.

The query operation is in pool resolution which updates all the pool
counter raw data by one operation.
