| 4 | Subject: [PATCH] hostapd: mtk: add extension IE list for non-inherit IE in |
| 5 | mbssid |
| 6 | |
| 7 | Certain clients do not scan all non tx profiles due to absence of |
| 8 | element ID extension list which is mandatory field in non inheritance |
| 9 | IE. Non inheritance Element ID is followed by extension element ID. |
| 10 | Length is expected to be mentioned. Currently we do not support any |
| 11 | extension element and hence filling length as 0. |
