Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.
It is safe to call GetObject() from within this method.

Return the value of the Queue Size subfield of the last QoS Data or QoS Null frame received from the station with the given MAC address and belonging to the given TID.
The Queue Size value is the total size, rounded up to the nearest multiple of 256 octets and expressed in units of 256 octets, of all MSDUs and A-MSDUs buffered at the STA (excluding the MSDU or A-MSDU of the present QoS Data frame). A queue size value of 254 is used for all sizes greater than 64 768 octets. A queue size value of 255 is used to indicate an unspecified or unknown size. See Section 9.2.4.5.6 of 802.11-2016

This method acts as the MacRxMiddle receive callback and is invoked to notify us that a frame has been received.
The implementation is intended to capture logic that is going to be common to all (or most) derived classes. Specifically, handling of Block Ack management frames is dealt with here.
This method will need, however, to be overridden by derived classes so that they can perform their data handling before invoking the base version.
