Detailed Description

Test release of sequence numbers upon CTS timeout in multi-link operations.

In this test, an AP MLD and a non-AP MLD setup 3 links. Usage of RTS/CTS protection is enabled for frames whose length is at least 1000 bytes. The AP MLD receives a first set of 4 packets from the upper layer and sends an RTS frame, which is corrupted at the receiver, on a first link. When the RTS frame is transmitted, the AP MLD receives another set of 4 packets, which are transmitted after a successful RTS/CTS exchange on a second link. In the meantime, a new RTS/CTS exchange is successfully carried out (on the first link or on the third link) to transmit the first set of 4 packets. When the transmission of the first set of 4 packets starts, the AP MLD receives the third set of 4 packets from the upper layer, which are transmitted after a successful RTS/CTS exchange.

This test checks that sequence numbers are correctly assigned to all the MPDUs carrying data.
