| Subject: wcn36xx: Fix HT40 capability for 2Ghz band |
| |
| From: Loic Poulain <loic.poulain@linaro.org> |
| |
| 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. |
