From: Leon Romanovsky <leonro@...lanox.com>

Changelog v0->v1:
 * Fixed typo in manual page (Gal)

Hi,

This is supplementary part of accepted to rdma-next kernel series,
that kernel series provided an option to get various counters: global
and per-objects.

Currently, all counters are printed in format similar to other
device/link properties, while "-p" option will print them in table like
format.

[leonro@...ver ~]$ rdma stat show
link mlx5_0/1 rx_write_requests 0 rx_read_requests 0 rx_atomic_requests
0 out_of_buffer 0 duplicate_request 0 rnr_nak_retry_err 0 packet_seq_err
0 implied_nak_seq_err 0 local_ack_timeout_err 0 resp_local_length_error
0 resp_cqe_error 0 req_cqe_error 0 req_remote_invalid_request 0
req_remote_access_errors 0 resp_remote_access_errors 0
resp_cqe_flush_error 0 req_cqe_flush_error 0 rp_cnp_ignored 0
rp_cnp_handled 0 np_ecn_marked_roce_packets 0 np_cnp_sent 0

[leonro@...ver ~]$ rdma stat show -p
