Subject: [PATCH] hostapd: Add element ID extension as part of non-inheritance
|
|
IE for 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.
