The rdma core library can map doorbell register in two ways,
depending on the environment variable "MLX5_SHUT_UP_BF":
- as regular cached memory, the variable is either missing or
set to zero. This type of mapping may cause the significant
doorbell register writing latency and requires explicit
memory write barrier to mitigate this issue and prevent
write combining.
- as non-cached memory, the variable is present and set to
not "0" value. This type of mapping may cause performance
impact under heavy loading conditions but the explicit write
memory barrier is not required and it may improve core
performance.
The new devarg is introduced "tx_db_nc", if this parameter is
set to zero, the doorbell register is forced to be mapped to
cached memory and requires explicit memory barrier after
writing to. If "tx_db_nc" is set to non-zero value the doorbell
will be mapped as non-cached memory, not requiring the memory
barrier. If "tx_db_nc" is missing the behaviour will be defined
by presence of "MLX5_SHUT_UP_BF" in environment. If variable
is missed the default value zero will be set for ARM64 hosts
and one for others.
In run time the code checks the mapping type and provides the
memory barrier after writing to tx doorbell register if it is
needed. The mapping type is extracted directly from the
uar_mmap_offset field in the queue properties.

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.
Pool minimum devX counter ID uses atomic operation.

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.

dependency() function to look for it, as it will automatically add it
to the Requires.private list if needed, to allow for static builds to
succeed for reverse dependencies of DPDK. Otherwise the recursive
dependencies are not parsed, and users doing static builds have to
resolve them manually by themselves.
When using this API avoid additional checks that are superfluous and

A PMD parameter (rxq_cqe_pad_en) is added to enable 128B padding of CQE on
RX side. The size of CQE is aligned with the size of a cacheline of the
core. If cacheline size is 128B, the CQE size is configured to be 128B even
though the device writes only 64B data on the cacheline. This is to avoid
unnecessary cache invalidation by device's two consecutive writes on to one
cacheline. However in some architecture, it is more beneficial to update
entire cacheline with padding the rest 64B rather than striding because
read-modify-write could drop performance a lot. On the other hand, writing
extra data will consume more PCIe bandwidth and could also drop the maximum
throughput. It is recommended to empirically set this parameter. Disabled

rte_flow has 'group' attribute and 'jump' action in order to support
multiple groups. This feature is known as multi-table support ('chain' in
linux TC flower) in general because a group means a table of flows. Example
commands are:
flow create 0 transfer priority 1 ingress
pattern eth / vlan vid is 100 / end
actions jump group 1 / end
flow create 0 transfer priority 1 ingress
pattern eth / vlan vid is 200 / end
actions jump group 2 / end
flow create 0 transfer group 1 priority 2 ingress
pattern eth / vlan vid is 100 /
ipv4 dst spec 192.168.40.0 dst prefix 24 / end
actions drop / end
flow create 0 transfer group 1 priority 2 ingress
pattern end
actions of_pop_vlan / port_id id 1 / end
flow create 0 transfer group 2 priority 2 ingress
pattern eth / vlan vid is 200 /
ipv4 dst spec 192.168.40.0 dst prefix 24 / end
actions of_pop_vlan / port_id id 2 / end
flow create 0 transfer group 2 priority 2 ingress
pattern end
actions port_id id 2 / end
With theses flows, if a packet having vlan 200 and src_ip as 192.168.40.1,
this packet will firstly hit the 1st flow. Then it will hit the 5th flow
because of the 'jump' action. As a result, the packet will be forwarded to
port 2 (VF representor) with vlan tag being stripped off. If the packet had
vlan 100 instead, it would be dropped by the 3rd flow.
