[dpdk-dev] [PATCH v2] net/mlx5: flow counters support on the Linux-rdma v19 base

Viacheslav Ovsiienko viacheslavo at mellanox.com
Wed Oct 17 15:53:58 CEST 2018


Mellanox mlx5 PMD supports Flow Counters via Verbs library.
The current implementation is based on the Mellanox proprietary
Verbs library included in MLNX OFED packages. The Flow Counter
support is recently added into linux-rdma release (v19),
so the mlx5 PMD update is needed to provide Counter feature
on the base of linux-rdma.

mlx5 PMD can be compiled with MLNX OFED or linux-rdma v19+
and provide flow counters for both.

Signed-off-by: Viacheslav Ovsiienko <viacheslavo at mellanox.com>

---
v2:
- rebased on top of master-net-mlx branch
- new compilation flags are introduced:
    - HAVE_IBV_DEVICE_COUNTERS_SET_SUPPORT_V42, kernel/verbs
      library provides the flow counter support in style of
      MLNX_OFED_4.2 to MLNX_OFED_4.4
    - HAVE_IBV_DEVICE_COUNTERS_SET_SUPPORT_V45, kernel/verbs
      library provides the flow counter support in style of
      MLNX_OFED_4.5 or higher

v1:
- http://patches.dpdk.org/patch/45972/
