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.
Reimplemented from ns3::Object.

This method is called if this device is an MLD to determine the MAC address of the affiliated STA used to communicate with the single link device having the given MAC address.
This method is overridden because its implementation depends on the type of station.

Initialize() implementation.
This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.
Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.

This method acts as the MacRxMiddle receive callback and is invoked to notify us that a frame has been received on the given link.
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.
The given link may be undefined in some cases (e.g., in case of QoS Data frames received in the context of a Block Ack agreement – because the BlockAckManager does not have to record the link each buffered MPDU has been received on); in such a cases, the value of linkId should be WIFI_LINKID_UNDEFINED.

Set the AID field of the given Association Response frame.
In case of multi-link setup, the selected AID value must be assigned to all the STAs corresponding to the setup links. The AID value is selected among the AID values that are possibly already assigned to the STAs affiliated with the non-AP MLD we are associating with. If no STA has an assigned AID value, a new AID value is selected.

mpdu | the MPDU that we successfully sent |
The STA is affiliated with an MLD. From Sec. 35.3.7.1.4 of 802.11be D3.0: When a link becomes enabled for a non-AP STA that is affiliated with a non-AP MLD after successful association with an AP MLD with (Re)Association Request/Response frames transmitted on another link [...], the power management mode of the non-AP STA, immediately after the acknowledgement of the (Re)Association Response frame [...], is power save mode, and its power state is doze.
Thus, STAs operating on all the links but the link used to establish association transition to power save mode.
