802.11e priority
To provide QoS services on WLAN, the 802.11e standard was developed. IEEE 802.11e is a MAC-layer
enhancement to IEEE 802.11. IEEE 802.11e adds a 2-byte QoS Control field to the 802.11e MAC frame
header. The 3 bits of the QoS control field represents the 802.11e priority, which is in the range of 0 to
7.

EXP values
The EXP field is in MPLS labels for MPLS QoS purposes.
