While flow attaches the meter handle, the meter id can be the unique tag
for the flow to get the meter handle. It's no need for flow to save the
pointer of the meter handle.
Save the meter id instead of pointer helps reduce the size for rte flow
structure.
As the supported maximum meter rule is 4K, uint16_t type is selected for
the meter id.

Currently, the mlx5_flow_handle struct is not fully aligned and has some
bits wasted. The members can be optimized and reorganized to save memory.
1. As metadata and meter is sharing the same flow match id, now the flow
id is limited to 24 bits due to the 8 MSBs are used as for the meter
color. Align the flow id to other bit members to 32 bits to save the
mlx5 flow handle memory.
2. The vlan_vf in struct mlx5_flow_handle_dv was already moved to struct
mlx5_flow_handle. Remove the legacy vlan_vf in struct
mlx5_flow_handle_dv.
3. Reorganize the vlan_vf in mlx5_flow_handle with member SILIST_ENTRY
next to make it align with 8 bytes.
4. Reorganize the header modify in mlx5_flow_handle_dv to ILIST_ENTRY
next to make it align to with bytes.
5. Introduce __rte_pack attribute to make the struct tightly organized.
It will totally save 20 bytes memory for mlx5_flow_handle struct.
For the resource objects which are converted to indexed, align the names
with the prefix of rix_.

Currently, the memory allocated by rte_malloc() also introduced more
than 64 bytes overhead. It means when allocate 64 bytes memory, the
real cost in memory maybe double. And the libc malloc() overhead is 16
bytes, If users try allocating millions of small memory blocks, the
overhead costing maybe huge. And save the memory pointer will also be
quite expensive.
Indexed memory pool is introduced to save the memory for allocating
huge amount of small memory blocks. The indexed memory uses trunk and
bitmap to manage the memory entries. While the pool is empty, the trunk
slot contains memory entry array will be allocated firstly. The bitmap
in the trunk records the entry allocation. The offset of trunk slot in
the pool and the offset of memory entry in the trunk slot compose the
index for the memory entry. So, by the index, it will be very easy to
address the memory of the entry. User saves the 32 bits index for the
memory resource instead of the 64 bits pointer.
User should create different pools for allocating different size of
small memory block. It means one pool provides one fixed size of small
memory blocked allocating.

This patch allows to display flow stats in extended stats.
To do this, DMA-able memory is registered with the FW during device
initialization. Then the driver uses an alarm thread to query the
per flow stats using the HWRM_CFA_COUNTER_QSTATS HWRM command at
regular intervals and stores it locally which will be displayed
when the application queries the xstats.
The DMA-able memory is unregistered during driver cleanup.
This functionality can be enabled using the flow-xstat devarg and
will be disabled by default. The intention behind this is to allow
stats to be displayed for all the flows in one shot instead of
querying one at a time.

Defer shadow ring update introduces functional issue which has been
described in Eugenio's fix patch.
The current implementation of vhost_net in packed vring tries to fill
the shadow vector before send any actual changes to the guest. While
this can be beneficial for the throughput, it conflicts with some
bufferfloats methods like the linux kernel napi, that stops
transmitting packets if there are too much bytes/buffers in the
driver.
It also introduces performance issue when frontend run much faster than
backend. Frontend may not be able to collect available descs when shadow
update is deferred. That will harm RFC2544 throughput.
Appropriate choice is to remove deferred shadowed update method.
Now shadowed used descs are flushed at the end of dequeue function.
