background traffic,
management and priority traffic.

This method is called only once by Object::Initialize.

If the user calls Object::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.

Parameters

packet	the packet to send.
to	the address to which the packet should be sent.
from	the address from which the packet should be sent.

The packet should be enqueued in a tx queue, and should be dequeued as soon as the channel access function determines that access is granted to this MAC. The extra parameter "from" allows this device to operate in a bridged mode, forwarding received frames without altering the source address.

standard the phy standard to be used

This method is called by ns3::WifiMac::ConfigureStandard to complete the configuration process for a requested phy standard.

This method may be overriden by a derived class (e.g., in order to apply DCF or EDCA parameters specific to the usage model it is dealing with), in which case the reimplementation may choose to deal with certain values in the WifiPhyStandard enumeration, and chain up to this implementation to deal with the remainder.
