net/mlx5e: Monitor counters commands support
new file monitor_stats.c for the new API.
add arm_monitor_counter new command support.
add set_monitor_counter new command support.
The device can monitor specific counters and provide an event to notify
when these counters are changed.
The monitoring is done in best effort manner where the minimum
notification period is 200 ms, however when the device is loaded, the
notification might be delayed.
To configure the required counters to be monitored, the
SET_MONITOR_COUNTER command shall be used with a list of counters to be
monitored.
The device firmware can monitor up to HCA_CAP.max_num_of_monitor_counters.
The configuration is done based on counter type (such as ppcnt, q counter,
etc) and additional param according to the type of counter selected.
Upon monitor counter change, the device will generate
Monitor_Counter_Change event.
The device will not generate new events unless the driver re-arms the
monitoring functionality, using the ARM_MONITOR_COUNTER command.
