This patch adds the ability to get the name, index and status of all counters for each link through RDMA netlink. This can be used for user-space to get the current optional-counter mode. Examples: $ rdma statistic mode link rocep8s0f0/1 optional-counters cc_rx_ce_pkts $ rdma statistic mode supported link rocep8s0f0/1 supported optional-counters cc_rx_ce_pkts,cc_rx_cnp_pkts,cc_tx_cnp_pkts link rocep8s0f1/1 supported optional-counters cc_rx_ce_pkts,cc_rx_cnp_pkts,cc_tx_cnp_pkts Link: https://lore.kernel.org/r/20211008122439.166063-8-markzhang@nvidia.com Signed-off-by: Aharon Landau <aharonl@nvidia.com> Signed-off-by: Neta Ostrovsky <netao@nvidia.com> Signed-off-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Mark Zhang <markzhang@nvidia.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
