To avoid custom kernel patch linking, the user is now guided to the AWS

Memory regions (MRs) were allocated in one chunk of memory with a
mempool registration object. However, MRs can be reused among
different mempool registrations.
When the registration that allocated the MRs originally was
destroyed, the dangling pointers to the MRs could be left in other
registrations sharing these MRs.
Splitting the memory allocation of registration structure and MRs in
this commit solves this pointer reference issue.

This patch fixes segfault which was triggered when port, with indirect
actions created, was closed. Segfault was occurring only when
RTE_LIBRTE_MLX5_DEBUG was defined. It was caused by redundant decrement
of RX queues refcount:
- refcount was decremented when port was stopped and indirect actions
were detached from RX queues (port stop),
- refcount was decremented when indirect actions objects were destroyed
(port close or destroying of indirect action).
This patch fixes behavior. Dereferencing Rx queues is done if and only
if indirect action is explicitly destroyed by the user or detached on
port stop. Dereferencing Rx queues on action destroy operation depends
on an argument to the wrapper of indirect action destroy operation,
introduced in this patch.

In a meter hierarchy, all the meters are marked with having RSS if

When validating a flow rule with meter hierarchy, the RSS action
should not be fetched from the current meter if it is not the final

The fate action union is next meter ID instead of the pointer to the
RSS action. By using the final meter in the hierarchy, the flow rule

If there are sample action and the meter action in the same flow,
mlx5 PMD performs several levels of splitting. For example, sampling
feature splits the original flow into prefix subflow with sample action,
and suffix subflow with the rest of actions. Then, metering feature
splits the sampling suffix subflow into its own meter subflows.
If mark action was added before the sample and meter action, the
flow mark flag was kept in the sample subflows but reset on
handling the metering split, causing the flow mark value missed.
This patch keeps the flow mark flag of previous subflow, and then
the following meter subflows handle the flow mark correctly.

Mempool registration was not correctly processing
mempools with RTE_PKTMBUF_F_PINEND_EXT_BUF flag set
("pinned mempools" for short), because it is not known
at registration time whether the mempool is a pktmbuf one,
and its elements may not yet be initialized to analyze them.
Attempts had been made to recognize such pools,
but there was no robust solution, only the owner of a mempool
(the application or a device) knows its type.
This patch extends common/mlx5 registration code
to accept a hint that the mempool is a pinned one
and uses this capability from net/mlx5 driver.
1. Remove all code assuming pktmbuf pool type
or trying to recognize the type of a pool.
2. Register pinned mempools used for Rx
and their external memory on port start.
Populate the MR cache with all their MRs.
3. Change Tx slow path logic as follows:
3.1. Search the mempool database for a memory region (MR)
by the mbuf pool and its buffer address.
3.2. If not MR for the address is found for the mempool,
and the mempool contains only pinned external buffers,
perform the mempool registration of the mempool
and its external pinned memory.
3.3. Fall back to using page-based MRs in other cases
(for example, a buffer with externally attached memory,
but not from a pinned mempool).

The mlx5 PMD introduced the table id attribute to allow multiple
flow tables on the same table level for flow metering, there can be
multiple flow table objects with the same table level but different
table ids.
If the extended metadata mode is enabled, all flows containing
destination Queue/RSS actions are split into two subflows - prefix one
jumps to the MLX5_FLOW_MREG_CP_TABLE_GROUP flow table to copy
MARK action data, and suffix one to perform the destination Queue/RSS
action. The table_id for the jump in the metadata split prefix flow
is always 0.
If flow itself was the metering split suffix subflow the table id was
set to 1 in the flow split structure and the metadata split suffix
subflow was created in the table with wrong table id, causing the
metadata suffix flow mismatch.
This patch resets the table id to 0 while creating the metadata
suffix flows.
