Date: Wed, 24 Aug 2022 23:54:05 +0200 From: Aleksander Jan Bajkowski <olek2@...pl> To: hauke@...ke-m.de, davem@...emloft.net, edumazet@...gle.com, kuba@...nel.org, pabeni@...hat.com, olek2@...pl, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH net v3 0/3] net: lantiq_xrx200: fix errors under memory pressure This series fixes issues that can occur in the driver under memory pressure. Situations when the system cannot allocate memory are rare, so the mentioned bugs have been fixed recently. The patches have been tested on a BT Home router with the Lantiq xRX200 chipset. Changelog: v3: - removed netdev_err() log from the first patch v2: - the second patch has been changed, so that under memory pressure situation the driver will not receive packets indefinitely regardless of the NAPI budget, - the third patch has been added.
