Detailed Description

Test for A-MSDU and A-MPDU aggregation.

This test aims to check that the packets passed to the MAC layer (on the sender side) are forwarded up to the upper layer (on the receiver side) when A-MSDU and A-MPDU aggregation are used. This test checks that no packet copies are performed, hence packets can be tracked by means of a pointer.

In this test, an HT STA sends 8 packets (each of 1000 bytes) to an HT AP. The block ack threshold is set to 2, hence the first packet is sent as an MPDU containing a single MSDU because the establishment of a Block Ack agreement is not triggered yet. The maximum A-MSDU size is set to 4500 bytes and the maximum A-MPDU size is set to 7500 bytes, hence the remaining packets are sent in an A-MPDU containing two MPDUs, the first one including 4 MSDUs and the second one including 3 MPDUs.
