yes, it should have some flag/logic to check whether it is BIGTK.
If you know it, you can tell me. :)

Uh, actually, we don't have a secure indication of BIGTK getting used
until after the 4-way-HS.

Yes, the lower driver also have the max power limit itself. If power
calulated
from the fake beacon is bigger than the max power limit, then it will 
be
ignored.

Right.

The Transmit Power Envelope is not existed in the assoc response, it 
is
existed
in beacon. So it can not use assoc response.

Right.


Given this discussion, I think we should just leave it as is, and 
simply
not assume that the TPE is protected by beacon protection or such. 
There
are a number of other similar parameters, and doing some real 
protection
at this level would likely require further spec changes.

Thanks.
I will leave it as is without change for BIGTK.
I will change others patch and send new version.
