Imagine an ESS consisting of several APs in a switched wired network. Client
roams from one AP to another. In order to update the FDB of the switches, a
packet with the client MAC address needs to be originated from the ethernet
interface of the AP the client has associated to, even if the client does not
create traffic at the moment.
It's part of 802.11F.
