Detailed Description

Make sure that the ADDBA handshake process is protected.

The scenario considers an access point and a station. It utilizes ReceiveListErrorModel to drop by force ADDBA request on STA or ADDBA response on AP. The AP sends 5 packets of each 1000 bytes (thus generating BA agreement), 2 times during the test at 0.5s and 0.8s. We only drop the first ADDBA request/response of the first BA negotiation. Therefore, we expect that the packets still in queue after the failed BA agreement will be sent with normal MPDU, and packets queued after that should be sent with A-MPDU.

This test consider 2 cases:

ADDBA request packets are blocked on receive at STA, triggering transmission failure at AP
ADDBA response packets are blocked on receive at AP, STA stops retransmission of ADDBA response
