C++ definition

Used in 802.11 infrastructure mode: handles management frames for a station (STA).

This module accepts commands such as Scan, Authenticate, Deauthenticate, Associate, Reassociate, Deassociate from a connected agent module, and carries out the requested action by sending/receiving management frames, switching channels, etc.

It implements both active and passive scanning (where active means sending Probe frames). The authentication process is simulated by exchanging dummy messages, i.e. there is no actual cryptography or its detailed simulation involved.

Relies on the MAC layer (~Ieee80211Mac) for reception and transmission of frames.
