Mark Zhang 887fc739eb rdma: Add rdma statistic counter per-port auto mode support 
With per-QP statistic counter support, a user is allowed to monitor
specific QPs categories, which are bound to/unbound from counters
dynamically allocated/deallocated.

In per-port "auto" mode, QPs are bound to counters automatically
according to common criteria. For example a per "type"(qp type)
scheme, where in each process all QPs have same qp type are bind
automatically to a single counter.
Currently only "type" (qp type) is supported. Examples:

$ rdma statistic qp set link mlx5_2/1 auto type on
$ rdma statistic qp set link mlx5_2/1 auto off

Mark Zhang 1b2ca7ada7 rdma: Add get per-port counter mode support 
Add an interface to show which mode is active. Two modes are supported:
- "auto": In this mode all QPs belong to one category are bind automatically
  to a single counter set. Currently only "qp type" is supported;
- "manual": In this mode QPs are bound to a counter manually.

Examples:
$ rdma statistic qp mode
0/1: mlx5_0/1: qp auto off
1/1: mlx5_1/1: qp auto off
2/1: mlx5_2/1: qp auto type on
3/1: mlx5_3/1: qp auto off

$ rdma statistic qp mode link mlx5_0
0/1: mlx5_0/1: qp auto off

Mark Zhang 5937552b42 rdma: Add "stat qp show" support 
This patch presents link, id, task name, lqpn, as well as all sub
counters of a QP counter.
A QP counter is a dynamically allocated statistic counter that is
bound with one or more QPs. It has several sub-counters, each is
used for a different purpose.

Examples:
$ rdma stat qp show
link mlx5_2/1 cntn 5 pid 31609 comm client.1 rx_write_requests 0
rx_read_requests 0 rx_atomic_requests 0 out_of_buffer 0 out_of_sequence 0
