Detailed Description

Test for issue 211 (https://gitlab.com/nsnam/ns-3-dev/-/issues/211)

This test aims to check that the transmission of data frames (under a Block Ack agreement) resumes after a period in which the connectivity between originator and recipient is interrupted (e.g., the station moves away and comes back). Issue 211 revealed that MSDUs with expired lifetime were not removed from the wifi MAC queue if the station had to transmit a Block Ack Request. If the connectivity was lost for enough time, the wifi MAC queue could become full of MSDUs with expired lifetime, thus preventing the traffic control layer to forward down new packets. At this point, the station gave up transmitting the Block Ack Request and did not request channel access anymore.
