64825827ae RDMA/mlx5: Separate counters from main.c 
There are number of counters types supported in mlx5_ib: HW counters,
congestion counters, Q-counters and flow counters. Almost all supporting
code was placed in main.c that made almost impossible to maintain the code
anymore. Let's create separate code namespace for the counters to easy
future generalization effort.

5f62a521ff RDMA/mlx5: Set ECE options during modify QP 
The most common way to set ECE option will be during modify QP command in
INIT2RTR, RTR2RTS and RTS2RTS stages, so update mlx5 to support it.

The new bit in the comp_mask is needed to mark that kernel supports ECE
and can receive data instead of "reserved" field in the struct
mlx5_ib_modify_qp.

3e09a427ae RDMA/mlx5: Get ECE options from FW during create QP 
Supported ECE options are returned from FW in the create_qp phase and zero
means that field is not valid. Such default value allows us to reuse
reserved field without worries about comp_mask.

Update create QP API to return ECE options.

333fbaa025 net/mlx5: Move QP logic to mlx5_ib 
The mlx5_core doesn't need any functionality coded in qp.c, so move
that file to drivers/infiniband/ be under mlx5_ib responsibility.
