Disconnect a wireless client on an atheros-based access point
This command will disconnect the user whose mac was specified from the current list of clients from the wireless network when the network card is working in access point mode. Works on atheros-based access points which use the madwifi driver (not sure, but don't think it will work on access points which are not atheros-based, as it uses the atheros's iwpriv extensions). It will not prevent the user from reconnecting to the network, but may force the user to roam to another AP, with stronger signal.
