Detailed Description

Test update of BA starting sequence number after ADDBA Response timeout in multi-link operations.

In this test, an AP MLD and a non-AP MLD setup 2 links. The AP MLD has a QoS data frame to transmit to the non-AP MLD, which triggers the establishment of a BA agreement. When the ADDBA Request frame is received by the non-AP MLD, transmissions of the non-AP MLD are blocked to put the transmission of the ADDBA Response on hold. The goal is to mimic a delay in getting channel access due to, e.g., other devices grabbing the medium. When the ADDBA Response timer at the AP MLD expires, transmissions of the non-AP MLD are unblocked, so that the AP MLD sends the QoS data frame (protected by RTS, but the test works without RTS as well, and using Normal acknowledgment) on one link and the non-AP MLD sends the ADDBA Response on the other link. The transmission of the QoS data frame is then corrupted. We verify that:

when the AP MLD receives the ADDBA Response, the BA starting sequence number is set to the sequence number of the QoS data frame which is inflight
the QoS data frame is retransmitted and received by the non-AP MLD
