What are two things that an access point （AP） does when it receives an 802.11 frame from a Wi-Fi Multimedia （WMM） client？ （）

• A、EAP-FASTEAP-FAS Access Point Protocol （LWAPP） packet is used to generate an 802.1 p priority value in the packets， which are sent to an Ethernet switch by the controllers.
• B、The AP will police the 802.1 le priority value to ensure it does not exceed the maximum value allowed for the QoS policy that is assigned to that client.
• C、Once the LWAPP packet is received， the AP generates the IEEE 802.1 p priority value.
• D、The AP will map the 802.11e priority value to the DSCP value.
• E、The AP will map the DSCP value to the outer LWAPP frame.
