From: Stefan Wahren <stefan.wahren@i2se.com> stable inclusion from stable-5.10.65 commit a67c66c1bb1244c0a9028fa1003e99a264a1abd8 bugzilla: 182361 https://gitee.com/openeuler/kernel/issues/I4EH3U Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 429205da6c834447a57279af128bdd56ccd5225e ] 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.
