Message-Id: <20230412124737.2243527-4-vladimir.oltean@nxp.com> Date: Wed, 12 Apr 2023 15:47:32 +0300 From: Vladimir Oltean <vladimir.oltean@....com> To: netdev@...r.kernel.org Cc: Andrew Lunn <andrew@...n.ch>, Florian Fainelli <f.fainelli@...il.com>, "David S. Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com>, Claudiu Manoil <claudiu.manoil@....com>, Alexandre Belloni <alexandre.belloni@...tlin.com>, UNGLinuxDriver@...rochip.com, Colin Foster <colin.foster@...advantage.com>, linux-kernel@...r.kernel.org Subject: [PATCH net-next 3/8] net: mscc: ocelot: debugging print for statistics regions 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.
