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; Signed-off-by: NParav Pandit <parav@mellanox.com> Reviewed-by: NEli Cohen <eli@mellanox.com> Reviewed-by: NDaniel Jurgens <danielj@mellanox.com> Signed-off-by: NLeon Romanovsky <leon@kernel.org> Signed-off-by: NDoug Ledford <dledford@redhat.com>
