Wi-Fi AP state machine
Handle association, dis-association and authentication, of STAs within an infrastructure BSS.
ns3::ApWifiMac is accessible through the following paths with Config::Set and Config::Connect:
No TraceSources are defined for this type.

This method is called to de-aggregate an A-MSDU and forward the constituent packets up the stack. We override the WifiMac version here because, as an AP, we also need to think about redistributing to other associated STAs.
| aggregatedPacket | the Packet containing the A-MSDU. |
| hdr | a pointer to the MAC header for aggregatedPacket. |

This method is called by Object::Dispose or by the object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overriden 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.

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.

| packet | the packet to send. |
| to | the address to 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.

| packet | the packet to send. |

| 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.

This method acts as the MacRxMiddle receive callback and is invoked to notify us that a frame has been received. The implementation is intended to capture logic that is going to be common to all (or most) derived classes. Specifically, handling of Block Ack managment frames is dealt with here.
This method will need, however, to be overriden by derived classes so that they can perform their data handling before invoking the base version.
| packet | the packet that has been received. |
| hdr | a pointer to the MAC header of the received frame. |
