dd4bb90bc3 net/mlx5: use Netlink to enable promisc/allmulti mode
VF devices are not able to receive promisc or allmulti traffic unless it
fully requests it though Netlink.  This will cause the request to be
processed by the PF which will handle the request and enable it.

This requires the VF to be trusted by the PF.

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.

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:

fc5b160f3c net/mlx: fix debug build with gcc 6.1
With recent gcc versions, e.g. gcc 6.1, compilation of mlx drivers with
debug enabled produces lots of errors complaining that "pedantic" is
not a warning level that can be ignored.

error: ‘-pedantic’ is not an option that controls warnings [-Werror=pragmas]
 #pragma GCC diagnostic ignored "-pedantic"
                                 ^~~~~~~~~~~

These errors can be removed by changing the "-pedantic" to "-Wpedantic".

a48deada65 mlx5: allow operation in secondary processes
Secondary processes are expected to use queues and other resources
allocated by the primary, however Verbs resources can only be shared
between processes when inherited through fork().

This limitation can be worked around for TX by configuring separate queues
from secondary processes.

0497ddaac5 mlx5: add special flows for broadcast and IPv6 multicast
Until now, broadcast frames were handled like unicast. Moving the related
flow to the special flows table frees up the related unicast MAC entry.

542c21fb0f mlx5: use alternate method to configure promisc and allmulti modes
Promiscuous and allmulticast modes were historically enabled by adding
specific flows with types IBV_FLOW_ATTR_ALL_DEFAULT or
IBV_EXP_FLOW_ATTR_MC_DEFAULT to each hash RX queue, but this method is
deprecated.

- Promiscuous mode is now enabled by omitting destination MAC addresses from
  basic flow specifications.
- Allmulticast mode is now enabled by using flow specifications that match
  the broadcast bit in destination MAC addresses.

a76133214d mlx5: use separate indirection table for default hash Rx queue
The default hash RX queue handles packets that are not matched by more
specific types and requires its own indirection table of size 1 to work
properly.

This commit implements support for multiple indirection tables by grouping
their layout and properties in a static initialization table.

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).
