Its not guaranteed that counters gets enabled and mapped to all the default rules,
since the counters are scarce and driver follows a best effort approach.
The default rule serves as the primary packet steering rule for a specific PF or VF,
based on its DMAC address which is installed by AF driver as part of its initialization.
Sample command to read hit counters for default rule from debugfs is as follows,
cat /sys/kernel/debug/cn10k/npc/mcam_rules</p></td>
