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.

Send a Multi-STA Block Ack frame after the reception of some TB PPDUs.
txParams | the TX parameters for the Trigger Frame that solicited the TB PPDUs |
durationId | the Duration/ID field of the HE TB PPDU that elicited the Multi-STA Block Ack response |
In a BlockAck frame transmitted in response to a frame carried in HE TB PPDU under single protection settings, the Duration/ID field is set to the value obtained from the Duration/ID field of the frame that elicited the response minus the time, in microseconds between the end of the PPDU carrying the frame that elicited the response and the end of the PPDU carrying the BlockAck frame. Under multiple protection settings, the Duration/ID field in a BlockAck frame transmitted in response to a frame carried in HE TB PPDU is set according to the multiple protection settings defined in 9.2.5.2. (Sec. 9.2.5.7 of 802.11ax-2021)
