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.
