void ns3::WifiNetDevice::DoDispose ( void )

protectedvirtual

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 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.

Here is the caller graph for this function:

Address ns3::WifiNetDevice::GetMulticast ( Ipv4Address multicastGroup ) const

virtual

Make and return a MAC multicast address using the provided multicast group.

RFC 1112 says that an Ipv4 host group address is mapped to an Ethernet multicast address by placing the low-order 23-bits of the IP address into the low-order 23 bits of the Ethernet multicast address 01-00-5E-00-00-00 (hex). Similar RFCs exist for Ipv6 and Eui64 mappings. This method performs the multicast address creation function appropriate to the underlying MAC address of the device. This MAC address is encapsulated in an abstract Address to avoid dependencies on the exact MAC address format.

In the case of net devices that do not support multicast, clients are expected to test NetDevice::IsMulticast and avoid attempting to map multicast packets. Subclasses of NetDevice that do support multicasting are expected to override this method and provide an implementation appropriate to the particular device.

Parameters

multicastGroup The IP address for the multicast group destination of the packet.

Returns: The MAC multicast Address used to send packets to the provided multicast group.

Warning: Calling this method is invalid if IsMulticast returns not true.

void ns3::WifiNetDevice::NotifyNewAggregate ( void )

protectedvirtual

Notify all Objects aggregated to this one of a new Object being aggregated.

This function must be implemented in the stack that needs to notify other stacks connected to the node of their presence in the node.

This method is invoked whenever two sets of Objects are aggregated together. It is invoked exactly once for each Object in both sets. This method can be overriden by subclasses who wish to be notified of aggregation events. These subclasses must chain up to their base class NotifyNewAggregate() method.

It is safe to call GetObject() and AggregateObject() from within this method.

uint8_t ns3::WifiNetDevice::SelectQueue ( Ptr< QueueItem > item ) const

private

Determine the tx queue for a given packet.

Parameters

item	the packet

Modelled after the Linux function ieee80211_select_queue (net/mac80211/wme.c). A SocketPriority tag is attached to the packet (or the existing one is replaced) to carry the user priority, which is set to the three most significant bits of the DS field (TOS field in case of IPv4 and Traffic Class field in case of IPv6). The Access Category corresponding to the user priority according to the QosUtilsMapTidToAc function is returned.
