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.

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.

Note: in order to properly model out of band transmissions for OFDM, the guard band has been configured so as to expand the modeled spectrum up to the outermost referenced point in "Transmit spectrum mask" sections' PSDs of each PHY specification of 802.11-2016 standard. It thus ultimately corresponds to the current channel bandwidth (which can be different from devices max channel width).
This method is only relevant for SpectrumWifiPhy.

This map holds the supported PHY entities.
The set of parameters (e.g. mode) that this WifiPhy(-derived class) can support can be obtained through it.
When it comes to modes, in conversation we call this set the DeviceRateSet (not a term you'll find in the standard), and it is a superset of standard-defined parameters such as the OperationalRateSet, and the BSSBasicRateSet (which, themselves, have a superset/subset relationship).
Mandatory rates relevant to this WifiPhy can be found by iterating over the elements of this map, for each modulation class, looking for WifiMode objects for which WifiMode::IsMandatory() is true.

The trace source fired when the reception of the PHY payload (PSDU) begins.
This traced callback models the behavior of the PHY-RXSTART primitive which is launched upon correct decoding of the PHY header and support of modes within. We thus assume that it is sent just before starting the decoding of the payload, since it's there that support of the header's content is checked. In addition, it's also at that point that the correct decoding of HT-SIG, VHT-SIGs, and HE-SIGs are checked.
