| | 24 | When receiving a wireless MPDU, an 802.11 AP must filter on the type of packet and where it came from (i.e. transmitter address TA). In the event that the received MPDU is a data frame intended to be delivered to the wired Ethernet portal, it is passed off to the MAC High Framework's [wiki:../MACHighFramework/EthEncap Ethernet de-encapsulation] function before being transmitted via the Ethernet MAC and PHY. When a received frame is one of the many [http://en.wikipedia.org/wiki/IEEE_802.11#Management_Frames management frametypes], the AP honors the 802.11 standard's protocol for handshakes during the association process. This handshake is visualized in the above state diagram. |
