These mostly determine the MAX AMPDU length. I also want to determine
the minimum length, so
that I can set min=max and lock the AMPDU length.
Thank you,

As far as i know AMPDU length is determined by 3 constraints. Firs
maximum AMPDU length. second blockAck window (if there were losses
then this will play a role). Third is Max air time of the AMPDU which
is 4ms for some domain constraints. this comes into play MCS is low
and packet duration gets more than 4ms. See following function in
xmit.c for details

Hello,
I have seen questions regarding the length of an AMPDU and how to
change
the maximum AMPDU length.
However, I require to lock the AMPDU length at a specific value.
Changing the max length does not guarantee
that all AMPDUs have a fixed length, it can be anything between 1
to max
based on the rate of arrival of new frames.
Is there a mechanism to force the card to wait to have enough
frames so
that all AMPDUs have a fixed length that we specify? In other words, I
need all AMPDUs to aggregate X full length frames.
Thank you,
Ali
