Hi,
presently in code, the block ack policy is not sent by mac80211 to the
lower level driver via the ampdu_action callback.
The mac80211 while transmitting a block ack (ADDBA)request, hardcodes
the block ack methodology to immediate block ack.
on the receive side, the delayed block ack bit is checked along-with
the capability of the receiver station to support delayed block ack.
even if the station supports delayed block ack, mac80211 does not send
the ba_policy down to the driver.
should ba_policy be sent to the driver so that lower level drivers can
take a call as to send block ack response in a delayed manner at its
convenience?
looking forward to some information
thanks in advance
Vivek

Well, if you wanted to support it, you'd first have to change the
negotiation to actually ask for it, no?
