net/mlx5: optimize flow RSS struct

When destroy the flow with RSS, flow can invoke the queues information
from hrxq index table object, since the queue number and list are both
saved to the index table object. No need to save the duplicated data in

when create the flow with RSS action helps to save the memory for rte
flow.

net/mlx5: reorganize flow handle struct

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

real cost in memory maybe double. And the libc malloc() overhead is 16
bytes, If users try allocating millions of small memory blocks, the

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

backend. Frontend may not be able to collect available descs when shadow

net/mlx5: fix validation of push VLAN without full mask

Due the limitation of HW, when PMD create push VLAN action it needs to
know what exactly the value of VID/PCP.

PMD try to figure out them via:
  - of_set_vlan_vid/pcp actions
  - VLAN item in pattern
If none of above is provided, default value - zero is used.

However user will write rule like [1] which match on a range of VID and
without of_set_vlan_vid action and expect the VID will inherit from
original packet. This is not supported by HW currently. PMD will set VID
to default value - zero because it cannot figure out the exact value of
VID from VLAN item.

This is sort of misleading for some users.

In order to avoid this, PMD will spit out error for rule like [1] to
force user to provide explicit VID/PCP for new pushed VLAN headers.

net/mlx5: fix push VLAN action to use item info

Currently when PMD create push VLAN action it need to provide VID to HW
and PMD get VID value from item VLAN in pattern if there is no
of_set_vlan_vid action following.

When user create rule like [1], which has of_set_vlan_vid action
before of_push_vlan, the intention is to modify VID on existing VLAN
header and push a new VLAN header with VID _inherit_ from the previous
of_set_vlan_vid.

Currently the above is not covered by PMD, PMD always fetch the VLAN
information from item for of_push_vlan action.

Fix it by only fetch VLAN information from item when there is no
previous of_set_vlan_vid action.
