Expose new counters using the get_hw_stats callback. We expose the following counters: +---------------------+----------------------------------------+ | Name | Description | |---------------------+----------------------------------------| |sent_pkts | number of sent pkts | |---------------------+----------------------------------------| |rcvd_pkts | number of received packets | |---------------------+----------------------------------------| |out_of_sequence | number of errors due to packet | | | transport sequence number | |---------------------+----------------------------------------| |duplicate_request | number of received duplicated packets. | | | A request that previously executed is | | | named duplicated. | |---------------------+----------------------------------------| |rcvd_rnr_err | number of received RNR by completer | |---------------------+----------------------------------------| |send_rnr_err | number of sent RNR by responder | |---------------------+----------------------------------------| |rcvd_seq_err | number of out of sequence packets | | | received | |---------------------+----------------------------------------| |ack_deffered | number of deferred handling of ack | | | packets. | |---------------------+----------------------------------------| |retry_exceeded_err | number of times retry exceeded | |---------------------+----------------------------------------| |completer_retry_err | number of times completer decided to | | | retry | |---------------------+----------------------------------------| |send_err | number of failed send packet | +---------------------+----------------------------------------+ Signed-off-by: Yonatan Cohen <yonatanc@mellanox.com> Reviewed-by: Moni Shoua <monis@mellanox.com> Reviewed-by: Andrew Boyer <andrew.boyer@dell.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>
