RDMA/nldev: Add support to get status of all counters
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>
