common/mlx5: fix compatibility with OFED port query API

The compilation flag HAVE_MLX5DV_DR_DEVX_PORT depends on presence
of mlx5dv_query_devx_port routine in rdma-core library.

The mlx5dv_query_devx_port routine exists only in OFED versions
of rdma-core library and is being planned to be removed and replaced
with Upstream compatible mlx5dv_query_port.

As mlx5dv_query_devx_port is being removed all the dependencies on
the HAVE_MLX5DV_DR_DEVX_PORT compilation flag are reconsidered.

The new compilation flag HAVE_MLX5DV_DR_CREATE_DEST_IB_PORT is for
backward compatibility with older OFED versions.

common/mlx5: use new port query API if available

In order to get E-Switch vport identifiers the mlx5 PMD relies
on two approaches:
  [a] use port query API if it is provided by rdma-core library
  [b] otherwise, deduce vport ids from the related VF index
The latter is not reliable and may not work with newer kernel
drivers and in some configurations (LAG), causing E-Switch
malfunction. Hence, engaging the port query API is highly
desirable.

Depending on rdma-core version the port query API is:
  - very old OFED versions have no query API (approach [b])
  - rdma-core OFED < 5.5 provides mlx5dv_query_devx_port,
    HAVE_MLX5DV_DR_DEVX_PORT flag is defined (approach [a])
  - rdma-core OFED >= 5.5 has mlx5dv_query_port, flag
    HAVE_MLX5DV_DR_DEVX_PORT_V35 is defined (approach [a])
  - future OFED versions might remove mlx5dv_query_devx_port
    and HAVE_MLX5DV_DR_DEVX_PORT will not be defined
  - Upstream rdma-core < v35 has no port query API (approach [b])
  - Upstream rdma-core >= v35 has  mlx5dv_query_port, flag
    HAVE_MLX5DV_DR_DEVX_PORT_V35 is defined (approach [a])

In order to support the new mlx5dv_query_port routine, the
conditional compilation flag HAVE_MLX5DV_DR_DEVX_PORT_V35
is introduced by this patch. The flag HAVE_MLX5DV_DR_DEVX_PORT
is kept for compatibility with previous rdma-core versions.

Despite this patch is not a bugfix (it follows the introduced API
variation in underlying library), it resolves the compatibility
issue and is highly desired to be ported to DPDK LTS.

type whether it is internal or external exact match entry.

2. When a flow doesn't hit the offloaded rules, the default action is
to send it to the kernel (L2 driver interface). In order to do that,

3. Both active and default bit set need to considered to check if a

BNXT_ULP_CF_IDX_DEV_PORT_ID which is used to get the interface’s

net/bnxt: modify VXLAN decap for multichannel mode

The driver is using physical port id as the index into
the tunnel inner flow table. However, this will not work in case
of multichannel mode where multiple physical functions are going
to share the same physical port id.

When tunnel inner flow offload request comes before tunnel
outer flow offload request, the driver caches the tunnel inner flow
details and programs it in the hardware after installing the tunnel
outer flow in the hardware. If more than one tunnel inner flow arrives
before tunnel outer flow is offloaded, the driver rejects any such
tunnel inner flow offload requests.

This patch fixes the above two problems by
1. Using dpdk port id as the index to store tunnel inner info.
2. Caching any number of tunnel inner flow offload requests that come
