So the frame gets broadcasted throughout the broadcast domain, until the end device with a matching MAC address responds to the broadcast, thus giving the switch a new source address to add to its MAC table. It duplicates the frame to all Ethernetports, except the port it came from.
(In the 802.11 frame header, address 1 is the destination address, address 2 is the source address, address 3 is the BSSID of the network and address 4 is used for WDS, to indicate the transmitter address.) The provision for four MAC addresses in a frame is about the only thing covered by the 802.11 standards.
