The dependent patch looks OK, but I wonder why I don't see the build error.

mlx5_flow_dv.c has a big `#ifdef HAVE_IBV_FLOW_DV_SUPPORT` block

And `HAVE_IBV_FLOW_DV_SUPPORT` set:
if `infiniband/mlx5dv.h` has `mlx5dv_create_flow_action_packet_reformat()`

In the rdma-core I have this function is not set, so I guess I don't compile
this file at all.

What is the dependency to have `mlx5dv_create_flow_action_packet_reformat()`?
All the rdma-core versions I checked doesn't have this function, am I doing
something wrong? Or is direct verbs feature something not released yet?
