| 4 | Subject: [PATCH 087/126] mtk: hostapd: Fix Operating Mode Notification issue |
| 5 | in 2GHz |
| 6 | |
| 7 | If this patch is not applied, since the driver enables the |
| 8 | Operating Mode Notification feature, hostapd will enable the OMN bit |
| 9 | in the Extended Capabilities Element when constructing beacon. |
| 10 | However, this is not allowed on frequency bands that do not support |
| 11 | ieee80211ac, hence add this patch to fix this issue. |
