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.

Take necessary actions when a BlockAck is missed, such as scheduling a BlockAckReq frame or the retransmission of the unacknowledged frames.
psdu | the PSDU (BlockAckReq or A-MPDU) that solicited a BlockAck response | |
txVector | the TXVECTOR used to send the PSDU that solicited a BlockAck response | |
[out] | resetCw | true if we shall stop retransmitting the PSDU |
The BlockAckReq must be sent on the same link as the data frames to avoid issues. As an example, assume that an A-MPDU is sent on link 0, the BlockAck timer expires and the BlockAckReq is sent on another link (e.g., on link 1). When the originator processes the BlockAck response, it will not interpret a '0' in the bitmap corresponding to the transmitted MPDUs as a negative acknowledgment, because the BlockAck is received on a different link than the one on which the MPDUs are (still) inflight. Hence, such MPDUs stay inflight and are not retransmitted.

If the given MPDU contains a BlockAckReq frame (the duration of which plus the response fits within the given available time, if the latter is not Time::Min() and this is not the initial frame of a TXOP), transmit the frame and return true.
Otherwise, return false.

availableTime | the amount of time allowed for the frame exchange. Equals Time::Min() in case the TXOP limit is null |

Note that txParams is moved to m_txParams and hence is left in an undefined state.

Check if aggregating an MSDU to the current MPDU (as specified by the given TX parameters) does not violate the size and time constraints, while taking into account the possibly updated protection and acknowledgment methods.
If size and time constraints are met, the TX parameters are modified with the updated protection and acknowledgment methods.
