| Subject: [PATCH 31/54] mtk: hostapd: add extension IE list for non-inherit IE |
| in mbssid |
| |
| Certain clients do not scan all non tx profiles due to absence of |
| element ID extension list which is mandatory field in non inheritance |
| IE. Non inheritance Element ID is followed by extension element ID. |
| Length is expected to be mentioned. Currently we do not support any |
| extension element and hence filling length as 0. |
