Implements a basic MSDU aggregation policy, controlled by parameters such as the minimum number of subframes needed to compose an A-MSDU, the minimum length for the aggregated payload, the maximum A-MSDU size, etc.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Parameters

Name	Type	Default value	Description
subframeNumThreshold	int	-1	Minimum number of subframes needed to compose an A-MSDU. (-1 means it won't be checked)
aggregationLengthThreshold	int	-1	The minimum length for an aggregated payload necessary to create an A-MSDU (-1 means it won't be checked).
maxAMsduSize	int	4065	-1 means infinity
qOsCheck	bool	true	Turns on/off the check of the presence of the QoS flag (false means off -- this is needed for aggregation in DCF mode).
