The Station sets the above size to 0x40 if [[#NetworkInfo]]+0x13 is <0x3. The Authentication challenge is only used/enabled if that value is >=0x3, and [[#IUserLocalCommunicationService]] is being used.
The AccessPoint sets the above size to 0x0 if the +0x0 Type is <0x3. The AccessPoint will only use/enable the Authentication challenge when the +0x0 Type is >=0x3, and [[#IUserLocalCommunicationService]] is being used.
Station->AccessPoint frame, relative to +0x0 above (frame size depends on whether +0xAC is enabled):
