Subject[PATCH net-next 3/8] net: mscc: ocelot: debugging print for statistics regions
Date
To make it easier to debug future issues with statistics counters not
getting aggregated properly into regions, like what happened in commit
6acc72a43eac ("net: mscc: ocelot: fix stats region batching"), add some
dev_dbg() prints which show the regions that were dynamically
determined.
