Looks like I can play with pointers to the linear part as well. I am thinking about the following scenario: in DMG (60G), max. MSDU size is 7920, so one have to account for this when establishing BACK. Then, I foresee it will be popular that MTU will be configured to 1500 (Ethernet bridging, just laziness etc.), so actual aggregations on the air would be 5x smaller that it could be. Then, I'd like to aggregate 5 packets 1500 bytes each into A-MSDU prior to aggregating it to A_MPDU. Then, I'll have good A-MPDU size. But, having more then 2Gbps throughput, I need effective way to de-aggregate A-MSDU on Rx side.
