Hi @ayurkiv-nvda , there is another file change in PR #22224
device/mellanox/x86_64-mlnx_msn4700-r0/Mellanox-SN4700-V64/supporting_bulk_counter_groups
Is that intentional or a missing?

@bingwang-ms we have optimized counter initialization on 202412 and above. So, we don't need it anymore.

@ayurkiv-nvda could you confirm this does not cause the regression in #16202? Does "show queue counters" still show q7 counters with this change? @bingwang-ms for viz.

Discussed with @bingwang-ms, configuration will be added separately by internal script. @ayurkiv-nvda, please revert this change
