4d3267092a mlx5: add Rx CRC stripping configuration
Until now, CRC was always stripped by hardware. This feature can be
configured since MLNX_OFED >= 3.2.

d0087d760f mlx5: fix Rx checksum offload in non L3/L4 packets
Change rxq_cq_to_ol_flags() to set checksum flags according to packet type,
so for non L3/L4 packets the mbuf chksum_bad flags will not be set.

Fixes: 67fa62bc67 ("mlx5: support checksum offload")

Avoid dereferencing pointers twice to get to fast Verbs functions by
storing them directly in RX/TX queue structures.

948fd64bef mk: replace the combined library with a linker script
The physically linked-together combined library has been an increasing
source of problems, as was predicted when library and symbol versioning
was introduced. Replace the complex and fragile construction with a
simple linker script which achieves the same without all the problems,
remove the related kludges from eg mlx drivers.

Since creating the linker script is practically zero cost, remove the
config option and just create it always.

Based on a patch by Sergio Gonzales Monroy, linker script approach
initially suggested by Neil Horman.

2f97422e77 mlx5: support RSS hash update and get
First implementation of rss_hash_update and rss_hash_conf_get, those
functions still lack in functionality but are usable to change the RSS
hash key.  For now, the PMD does not handle an indirection table for
each kind of flow (IPv4, IPv6, etc.), the same RSS hash key is used
for all protocols.  This situation explains why the rss_hash_conf_get
returns the RSS hash key for all DPDK supported protocols and why the
hash key is set for all of them too.

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).

61bdf1e0e5 mlx5: use fast verbs interface for scattered Rx
This commit updates mlx5_rx_burst_sp() to use the fast verbs interface for
posting RX buffers just like mlx5_rx_burst(). Doing so avoids a loop in
libmlx5 and an indirect function call through libibverbs.

Note: recv_sg_list() is not implemented in the QP burst API, this commit is
only to prepare transition to the WQ-based API.

771fa900b7 mlx5: introduce new driver for Mellanox ConnectX-4 adapters
In its current state, this driver implements the bare minimum to initialize
itself and Mellanox ConnectX-4 adapters without doing anything else
(no RX/TX for instance). It is disabled by default since it is based on the
mlx4 driver and also depends on libibverbs.
