[PATCH net v2 0/3] net: lantiq_xrx200: fix errors under memory pressure
From: Aleksander Jan Bajkowski
Date: Mon Aug 15 2022 - 10:58:18 EST
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:
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.
