stable inclusion from linux-4.19.207 commit b754f6353bbe66fe03fccff7ddd4e8025e55e243
--------------------------------
[ 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.
