IB/mlx5: Support congestion related counters
This patch adds support to query the congestion related hardware counters
through new command and links them with other hw counters being available
in hw_counters sysfs location.
In order to reuse existing infrastructure it renames related q_counter
data structures to more generic counters to reflect q_counters and
congestion counters and maybe some other counters in the future.
New hardware counters:
* rp_cnp_handled - CNP packets handled by the reaction point
* rp_cnp_ignored - CNP packets ignored by the reaction point
* np_cnp_sent - CNP packets sent by notification point to respond to
CE marked RoCE packets
* np_ecn_marked_roce_packets - CE marked RoCE packets received by
notification point
It also avoids returning ENOSYS which is specific for invalid
system call and produces the following checkpatch.pl warning.
WARNING: ENOSYS means 'invalid syscall nr' and nothing else
+ return -ENOSYS;
