[PATCH net] net: qualcomm: fix QCA7000 checksum handling
From: Stefan Wahren <hidden>
Date: 2021-08-28 14:27:30
Subsystem:
networking drivers, qualcomm atheros qca7k ethernet driver, the rest · Maintainers:

Based on tests the QCA7000 doesn't support checksum offloading. So assume
ip_summed is CHECKSUM_NONE and let the kernel take care of the checksum
handling. This fixes data transfer issues in noisy environments.
