You are correct, iwlwifi driver will handle enable the h/w aggregation queue and based on the ampdu_action() and other condition such as sequence# to decide which queue the pkt shall belong to. All the real aggregation works are performed in the firmware.

I noticed that the ampdu_action() function is implemented by iwl_mac_ampdu_action() in these drivers; but as far as I can find, only the operations of start/stop tx and rx aggregation are implemented in the driver, so I guess that the aggregation of MPDU packets (concatenating them into a single block, sending BAR - block acknowledge request, sending the block containing aggregated MPDUs, and so on) are implemented in firmware. Is it so ?
