dbeba4cf18 net/mlx: prefix private structure
The private structure stored in rte_eth_dev->data->dev_private
was named "struct priv".
In order to ease code browsing, the structure is renamed
"struct mlx[45]_priv".

264713ba10 net/mlx5: fix ARM build
rdma-core v16 has a bug. The following compilation error occurs on ARM
hosts.

In file included
from drivers/net/mlx5/mlx5_glue.h:16:0,
from drivers/net/mlx5/mlx5_glue.c:11:
/usr/include/infiniband/mlx5dv.h:144:2: error: unknown type name 'off_t'
off_t   uar_mmap_offset;
^

As a temporary fix, sys/types.h is included in PMD. This has been fixed in
rdma-core v17. This can be removed when all the Linux distros are shipped
with rdma-core v17 or back-ported fix. As of now, RedHat 7.5 is known to
have rdma-core v16.

af4f09f282 net/mlx5: prefix all functions with mlx5
This change removes the need to distinguish unlocked priv_*() functions
which are therefore renamed using a mlx5_*() prefix for consistency.

At the same time, all functions from mlx5 uses a pointer to the ETH device
instead of the one to the PMD private data.

ffc905f3b8 ethdev: separate driver APIs
Create a rte_ethdev_driver.h file and move PMD specific APIs here.
Drivers updated to include this new header file.

There is no update in header content and since ethdev.h included by
ethdev_driver.h, nothing changed from driver point of view, only
logically grouping of APIs. From applications point of view they can't
access to driver specific APIs anymore and they shouldn't.

More PMD specific data structures still remain in ethdev.h because of
inline functions in header use them. Those will be handled separately.

it should be treated as *read only*.

This configuration struct will be used for the Tx/Rx queue setup to

In addition it will be used by the burst selection function to decide
on the best pkt burst to be used.

289ba0c0f5 ethdev: allow returning error on VLAN offload ops
Some devices may not support or fail setting VLAN offload
configuration based on dynamic circumstances so the
vlan_offload_set_t vector is modified to return an int so
the caller can determine success or not.

rte_eth_dev_set_vlan_offload is updated to return the
value provided by the vector when called along with restoring
the original offload configs on failure.

Existing vlan_offload_set_t vectors are modified to return
an int.  Majority of cases return 0 but a few that actually
can fail now return their failure codes.

Finally, a vlan_offload_set_t vector is added to virtio
to facilitate dynamically turning VLAN strip on or off.

43e9d9794c net/mlx5: support upstream rdma-core
This removes the dependency on specific Mellanox OFED libraries by
using the upstream rdma-core and linux upstream community code.
Both rdma-core upstream and Mellanox OFED are Linux user-space packages:
  1. Rdma-core is Linux upstream user-space package.(Generic)
  2. Mellanox OFED is Mellanox's Linux user-space package.(Proprietary)
The difference between the two are the APIs towards the kernel.

Support for x86-32 is removed due to issues in rdma-core library.
ICC compilation will be supported as soon as the following patch is
integrated in rdma-core:

ecc1c29df8 mlx5: refactor Rx code for the new verbs RSS API
The new Verbs RSS API is lower-level than the previous one and much more
flexible but requires RX queues to use Work Queues (WQs) internally instead
of Queue Pairs (QPs), which are grouped in an indirection table used by a
new kind of hash RX QPs.

Hash RX QPs and the indirection table together replace the parent RSS QP
while WQs are mostly similar to child QPs.

RSS hash key is not configurable yet.

Summary of changes:

- Individual DPDK RX queues do not store flow properties anymore, this info
  is now part of the hash RX queues.
- All functions affecting the parent queue when RSS is enabled or the basic
  queues otherwise are modified to affect hash RX queues instead.
- Hash RX queues are also used when a single DPDK RX queue is configured (no
  RSS) to remove that special case.
- Hash RX queues and indirection table are created/destroyed when device
  is started/stopped in addition to create/destroy flows.
- Contrary to QPs, WQs are moved to the "ready" state before posting RX
  buffers, otherwise they are ignored.
- Resource domain information is added to WQs for better performance.
- CQs are not resized anymore when switching between non-SG and SG modes as
  it does not work correctly with WQs. Use the largest possible size
  instead, since CQ size does not have to be the same as the number of
  elements in the RX queue. This also applies to the maximum number of
  outstanding WRs in a WQ (max_recv_wr).
