Hi,
Currently I am testing certified 11n stations(Broadcom) but not able to find any outgoing packets with Ack Policy set as BlockAck. All the packets are found to be having Normal Ack. Can any body tell me why I am not able to see any frames with Ack Policy set to Block Ack? How can i send a frame set to Block Ack.

Secondly when the Block Ack request(BAR) need to be tranmitted? One case may be once a block ack session is established through ADDBA request/response exchanges, may be when an AMPDU tranmission fails. What are the other criterias under which BAR should be send.

Thanks
Ajay
