From: Leon Romanovsky <leonro@xxxxxxxxxxxx> Hi, This is supplementary part of accepted to rdma-next kernel series, that kernel series provided an option to get various counters: global and per-objects. Currently, all counters are printed in format similar to other device/link properties, while "-p" option will print them in table like format.
