Subject: [dpdk-users] COUNT action not supported on mlx5
Date: Thu, 23 Jul 2020 10:37:33 -0700 [thread overview]
Message-ID: <CAAcwi39OpANYQrMvr8v_EWz_iTywfA1Vjwy-jSYM62BjFcuTEw@mail.gmail.com> (raw)
Hello,
I'm trying to query per-flow statistics using RTE_FLOW_ACTION_TYPE_COUNT on
a Mellanox ConnectX-5 port. I tried extending the flow_filtering sample
application with:
struct rte_flow_query_count count = {
.reset = 1,
.hits_set = 1,
.bytes_set = 1,
.hits = 0,
.bytes = 0,
};
// set attr, pattern, etc.
action[0].type = RTE_FLOW_ACTION_TYPE_COUNT;
action[0].conf = &count;
action[1].type = RTE_FLOW_ACTION_TYPE_QUEUE;
action[1].conf = &queue;
action[2].type = RTE_FLOW_ACTION_TYPE_END;
The call to rte_flow_validate() returns with -ENOTSUP, saying the flow
cannot be created because the count action is not supported. However, mlx5
documentation (https://doc.dpdk.org/guides/nics/mlx5.html#statistics)
states that mlx5 does indeed support attaching count actions. Without the
count action the flow rule configuration works fine.
I am using DPDK-20.05 and MLNX_OFED_LINUX-5.0-2.1.8.0, with a ConnectX-5
Virtual Function (could the VF be the issue?). What can be the cause of
this?
On a related note, is there any plan for mlx5 to support
RTE_FLOW_ITEM_TYPE_RAW?
Thanks,
