Detailed Description

Test BlockAckReq frame sent by a Block Ack originator after dropping QoS data frames.

In this test, a non-AP STA associates with an AP MLD with 2 links using either legacy association or ML setup. A Block Ack agreement is established first in the downlink direction; the AP MLD sends 2 data frames, which are both corrupted. When a timeout occurs at the AP MLD, the 2 data frames are dropped, thus the AP MLD sends a BlockAckReq to advance the recipient window. It is checked that the BlockAckReq has the correct link addresses and that the non-AP STA replies with a BlockAck having correct link addresses. Then, a Block Ack agreement is established in the uplink direction and the same pattern of actions are repeated (in the inverse direction).
