I am seeing a build failure of MLX5 driver on Debian testing (buster) with dpdk.org master branch.
This is using libibverbs-dev version 19.0-1 The failure is: mlx5_glue.h:94:11: error: ‘struct ibv_counter_set_init_attr’ declared inside parameter list will not be visible outside of this definition or declaration [-Werror] struct ibv_counter_set_init_attr *init_attr); ^~~~~~~~~~~~~~~~~~~~~~~~~ It looks like this is being caused because HAVE_IBV_DEVICE_COUNTERS_SET_SUPPORT is not set, but the header file does not have the counter stuff. The Makefile is generating this mlx5 autoconf file by looking for "enum IBV_FLOW_SPEC_ACTION_COUNT" in /usr/include/infiniband/verbs.h. This enum is present, but counters are not. $ grep IBV_FLOW_SPEC_ACTION /usr/include/infiniband/verbs.h IBV_FLOW_SPEC_ACTION_TAG = 0x1000, IBV_FLOW_SPEC_ACTION_DROP = 0x1001, IBV_FLOW_SPEC_ACTION_HANDLE = 0x1002, IBV_FLOW_SPEC_ACTION_COUNT = 0x1003,
