This patch introduces the "mode" command, which presents the enabled or
supported (when the "supported" argument is available) optional
counters.
An optional counter is a vendor-specific counter that may be
dynamically enabled/disabled. This enhancement of hwcounters allows
exposing of counters which are for example mutual exclusive and cannot
be enabled at the same time, counters that might degrades performance,
optional debug counters, etc.
Examples:
To present currently enabled optional counters on link rocep8s0f0/1:
$ rdma statistic mode link rocep8s0f0/1
link rocep8s0f0/1 optional-counters cc_rx_ce_pkts
To present supported optional counters on link rocep8s0f0/1:
$ rdma statistic mode supported link rocep8s0f0/1
link rocep8s0f0/1 supported optional-counters cc_rx_ce_pkts,cc_rx_cnp_pkts,cc_tx_cnp_pkts
