Mapping external memory via rte_vfio_container_dma_map()

fixes rte_vfio_container_dma_map() for secondary processes.

This patch updates the mlx5 glue library, new counter support
Verbs function pointers are added to the glue linking structure
mlx5_glue. This structure now contains the pointers to the both
versions of counter supporting functions due to compatibility
issues. Depending on configuration macros the functions perform
actual Verbs library calls or return an error with meaning
"feature is not supported" (NULL or ENOTSUP).

net/mlx5: relocate flow counters query function

The flow_verbs_query_count() is moved into the the group of counter
managing functions and renamed to flow_verbs_counter_query() in order
to be in unified fashion with others.

Also minor function modification is made to avoid unreachable code
warnings if there is no counter support at compile time.

net/mlx5: simplify flow counters support check

The redundant check of Flow counters support in runtime is removed.
The flag flow_counter_en is eliminated from the code. The Verbs
create counter function just returns an error if no counter
support presented in the system.

If there is no any of Flow counters configuration macro defined
the log message is emited, indicating the missing counter support.

mlx5_flow_validate_action_count() fuctnion is also updated due to
flow_counter_en flag removal.

6 years agonet/mlx5: introduce new flow counters configuration macro
Viacheslav Ovsiienko [Tue, 23 Oct 2018 10:04:12 +0000 (10:04 +0000)]
net/mlx5: introduce new flow counters configuration macro

The new configuration macro HAVE_IBV_DEVICE_COUNTERS_SET_V45 is
introduced. Both makefile and meson.build are changed.

Flow counter support code depends on the following configuration
macros:

- HAVE_IBV_DEVICE_COUNTERS_SET_V42 - is defined if system supports
  the "old" flow counters functionality, MLNX_OFED version from
  4.2 to 4.4 is required.

- HAVE_IBV_DEVICE_COUNTERS_SET_V45 - is defined if system supports
  the "new" flow counters functionality, MLNX_OVED 4.5 (or higher)
  or Linux rdma-core v19 (or higher) is required.

Neither HAVE_IBV_DEVICE_COUNTERS_SET_V42 nor
HAVE_IBV_DEVICE_COUNTERS_SET_V45 is defined if there is no
counters support.
