I just found IEEE 802.11-2007 subclause 9.10 which actually explains all
the block-ack business without aggregation, but I assume that
aggregation now just means that instead of sending
mpdu + sifs + (mpdu + sifs)* + blockackreq
you send simply
a-mpdu

I see nothing in 9.10 that supports the view that aggregation/block-ack
should create a new traffic stream.
