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.
This management module variant does not implement beacons, probes, authentication and association -- it simply treats all stations as associated all the time. This also means that you cannot use this module in a simulation that involves handovers; for that you need to use the full version, Ieee80211MgmtAP.
When simulating an AP that has other (Ethernet or wireless) interfaces as well, this module can be connected to a MACRelayUnit which performs bridging of Ethernet frames. This module will perform conversion from/to EtherFrame for MACRelayUnit.
This module never switches channels, that is, it will operate on the channel the physical layer is configured for (see channelNumber in Ieee80211Radio).
