A wait time for data frames. The wait time is measured in slots. Valid

A list to the algorithm that determines the initial random backoff wait
time (window) for retry of a transmission.
This value cannot be higher than the value of Maximum Contention
Window.
The upper limit (in milliseconds) for the doubling of the random backoff
value. This doubling continues until either the data frame is sent or the
Maximum Contention Window size is reached.
This value must be higher than the value of Minimum Contention
Window.
The TXOP Limit is a station EDCA parameter and only applies to traffic
flowing from the client station to the EAP.
The Transmission Opportunity (TXOP) is an interval of time, in
milliseconds, when a WME (Wireless Multimedia Extensions) client
station has the right to initiate transmissions onto the wireless medium
(WM) towards the EAP. The valid values are multiples of 32 between 0
and 8192.
With this option enabled, the EAP would not acknowledge frames
with QosNoAck. No Acknowledgment is recommended if VoIP
phones access the network through the EAP.
As a power management method, it can greatly improve the
energy-saving capacity of clients.
