From: Loic Poulain <loic.poulain@linaro.org> stable inclusion from stable-5.10.80 commit 3d62e1c9bc5575ac042748814a1d3d3e5cc967d6 bugzilla: 185821 https://gitee.com/openeuler/kernel/issues/I4L7CG Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 960ae77f25631bbe4e3aafefe209b52e044baf31 upstream. All wcn36xx controllers are supposed to support HT40 (and SGI40), This doubles the maximum bitrate/throughput with compatible APs. Tested with wcn3620 & wcn3680B.
