Priorities of 0 through 3 map to the low-priority channel; 4 through 7 to the
high-priority channel. The mappings are the same as 802.1p VLAN priorities.
Consistent with RFC 2474
CodePoint 0 is predefined to a fixed priority value of 0
(low-priority channel).
CodePoint 48 is predefined to a fixed priority value of 6 (high-priority
channel).
CodePoint 56 is predefined to a fixed priority value of 7 (high-priority
channel).
You cannot change any of these three fixed priority values. Among the
settable parameters, the priority values (and therefore the handling of packets
in the high- or low-priority channel) are set in the AP for all downlinks within
the sector and in the SM for each uplink.
