* \brief Return the MAC multicast base address used when mapping multicast
* groups to MAC multicast addresses.
*
* Typically when one constructs a multicast MAC addresses, some bits from
* the IP multicast group are copied into a corresponding MAC multicast
* group. In EUI-48, for example, the low order 23 bits of the multicast
* group are copied to the MAC multicast group base address.
*
* This method allows access to the underlying MAC multicast group base
* address. It is expected that in most cases, a net device client will
* allow the net device to perform the actual construction of the multicast
* address. Use of this method is discouraged unless you have a good reason
* to perform a custom mapping. You should prefer
* NetDevice::MakeMulticastAddress which will do the RFC-specified mapping
* for the net device in question.
*
* \return The multicast address supported by this net device.
*
* \warning Calling this method is invalid if IsMulticast returns not true.
* The method NS_ASSERTs if the device is not a multicast device.
