Used in 802.11 infrastructure mode: handles management frames for an access point (AP). It relies on a connected Ieee80211Mac for actual reception and transmission of frames.

When simulating an AP that has other (Ethernet or wireless) interfaces as well, this module can be connected to a IMacRelayUnit which performs bridging of Ethernet frames. This module will perform conversion from/to EtherFrame for IMacRelayUnit.

This module never switches channels, that is, it will operate on the channel the physical layer is configured for (see channelNumber in Ieee80211Radio).

This module checks if there is an other module connected above the management module (e.g. RelayUnit) and sends the frame there if the frame's destination is not on the associated station's list. Multicast frames are broadcasted on the wireless card and a copy sent also up to the relay unit so it can broadcast it on other interfaces.
