To: Doug Ledford; +Cc: linux-rdma-u79uwXL29TY76Z2rM5mHXA, Parav Pandit
From: Parav Pandit <parav-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>
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;

It looks like that I sent wrong patch again
https://git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma.git/commit/?h=testing/queue-next&id=5d94819cda09641954c002b8c11d50965cd230c6
I'll do my homework to find what broke in my scripts and flow and resubmit.
Thanks
